Remote temperature control. Remote control system for heating a country house, summer house or cottage Remote monitoring of the temperature in the country house

Today we will talk about the possibility of automating the control of heating boilers in country house. Indeed, today there is no problem to provide remote dispatching of household systems, including heating, providing savings and high level comfort.

Goals of remote control

How often does the average person country house suitable for heating boiler? If it is a gas or electric unit, then minimal attention is paid to it. Thanks to modern devices automation, autonomous operation of the boiler is possible for a very, very long time. Only in severe frosts do you want to turn on the light in order to feel this pleasant contrast even more strongly: outside the window there is snow and wind, and in the house it is warm and cozy. But remote dispatching exists, so what tasks does it solve?

You should start with the fact that there are two heating modes: economical and comfortable. If the tenants of the house are absent for 10-12 hours a day, why maintain the optimal 23 ° C, if you can set the temperature sufficient for safety indoor plants and pets? And if the system will work in a saving mode during the absence of the owners, how to ensure a quick access to the rated power so as not to return to a half-cooled house every time? Of course, you can use timing management, but a rare person can boast a clear and uniform schedule. So, the first goal of remote heating control is to quickly change the heating power.

Another aspect lies in the stability of the system. No matter how reliable and high quality boiler equipment, the probability of an accident is still not zero. A drop in pressure, a stop in circulation, gas leaks - potentially all of these phenomena are quite frightening. If the boiler room is left unattended for a long time, then remote dispatching provides its second important function - monitoring the system's performance and notifying the user about problems. Well, the third function is the ability to remotely troubleshoot or prevent the consequences of an accident.

Type of fuel and modes of operation

Electronics provides a huge range of solutions of different levels of complexity, including those controlled over long distances. However, there is a big difference in what type of heating system you have to deal with, this directly determines the completeness and cost of the equipment.

Easiest to manage electric boilers: one or more heating elements can be switched by a simple contact or solid-state relay. Additional switching can be used to control forced circulation devices. Neither gas leaks nor damping of the solid fuel combustion chamber can occur.

If gas is chosen as the source of energy for heating, the boiler room is classified as a high-risk facility. The reverse draft can put out the burner, which the faulty automation will safely ignore. Remote control will allow you to turn off the gas supply or re-ignite the boiler, and if this is not possible, drain the water from the system to prevent it from freezing.

More difficult than others to manage heating systems on solid fuel. Here, control over the automatic supply of fuel is required, it is extremely important to maintain constant circulation so that the coolant does not boil. But in this regard, dispatching devices cope with a bang: in the end, everything is controlled by electromechanical devices, and it is very easy to interfere in their work remotely.

Electric boilers

Remote control of an electric boiler is one of the most budgetary projects. Depending on the configuration and modes of operation of the system, several options can be offered.

For heating without power control, where the problem of freezing is not relevant, that is, for antifreeze hydraulic systems, as well as air and convection ones. In such cases, all tasks are solved primitively - by a "smart" socket that can receive GSM messages (Domovoy, Sokol). The price of the issue is on average from 300 to 1000 rubles, the difference in cost is due both to differences in quality and switched load, and the availability additional features. For example, a socket may have a built-in thermostat or timer, as well as an autonomous power source. Some models have the ability to connect to mobile devices for easier configuration of operating modes. Most products provide feedback to the user, in particular, such sockets are able to notify of the correct execution of the command or the absence of electricity at the facility.

For multi-stage boilers and other heating devices with several active elements, several sockets can be used, but it is better to install one multi-channel (Elgato, Polygator) - the so-called rebuter. These devices are available in a wide range of configurations - both conventional plug multipliers and DIN rail mounting. The principle of operation is the same: remote control of the load by sending SMS with an instruction code or a call. Here it is already possible to implement quite interesting operation algorithms, such as turning on an additional heating circuit with separate system thermal control. It will only be enough to make small changes to the electrical connection diagram of the boiler by connecting individual heating elements to different channels.

Gas boilers

Unlike electric, gas heating systems require remote dispatching not only to receive commands, but also to provide high-quality feedback. Since direct control of a high load is not required, the solutions of the class described above are not entirely applicable. The best way out of the situation would be to use a modular switch with 3-4 contact groups, controlled via one of the wired interfaces (RS-232, 1-wire, etc.). Messages can be transmitted both via a GSM channel and via communication with a PC installed at the facility. Usually, in order to increase reliability, a main and a backup channel are organized.

The price range for gas boiler room dispatching systems is incredibly wide. In the lower price segment, there are devices from budget "Ksitals" for 7-8 thousand rubles to more friendly to the unprepared user Segnetics for 15-20 thousand rubles. The middle link includes domestic automation complexes OWEN, a set of devices can cost 20-30 thousand rubles. The most complex systems costing more than 50-70 thousand rubles are used in modular boiler rooms common use: on the one hand, dispatching notifies the service organization about the status of the system, on the other hand, users control individual parts of the collector node at their discretion. Solutions of this kind are not just a set of devices “out of the box”, manufacturers of boiler room equipment such as ROSS and Viessman work in this category, providing the consumer with a comprehensive project and installing, configuring and maintaining the system by qualified personnel.

In essence, such devices are ordinary signaling units that have from 6 to 20 control zones and are capable of managing 3-5 groups of dry contacts. In total, there are two popular architectures of such systems. "Ksital", for example, are specialized boiler room automation units, which were originally designed to connect standard temperature sensors, gas pollution, smoke and flame detectors. In turn, systems such as Segnetics and ARIES are based on freely programmable controllers, which can be supplemented with communication devices and separate switching units. Their main feature- the ability to connect atypical sensors and control actuators of completely different types.

The main difference between the representatives of the latter group is the availability of a convenient user interface: Segnetics is easily configured when connected to a PC or mobile devices, but OWEN complexes require a more serious engineering approach, including writing your own firmware in high-level programming languages. Which choice to make for yourself depends on the complexity of the device of the boiler unit and the piping of the boiler room. So, the simplest Ksital block will be enough to fully control the operation of parapet and chimney boilers low power(up to 40 kW), ARIES is used in boiler rooms with parallel connection of units, or in centralized air heating and air conditioning systems.

Solid fuel heating control

Freely configurable control systems are optimally suited for solid fuel boilers and installations connected to biogas generation devices. The reason for this is obvious: such boiler houses were originally designed to work in the presence of an operator and, as a rule, have an individual scheme for setting operating modes.

So, for the simplest solid fuel boiler, it is necessary to adjust the inflow and draft, control the temperature of not only the air in the room, but also the coolant at the inlet and outlet of the boiler. Additionally, you should carefully monitor the operation of the circulation system by measuring the differential pressure at the inlet and outlet of the recirculation unit. The inclusion of gas analyzers in the complex will also not be superfluous; in addition, the temperature of the combustion products should be taken into account. A secondary function of such dispatching systems can be called the provision economical consumption fuel and optimal modes burning it, depending on the desired temperature and the weather outside.

It is important to emphasize that full direct control over each node of the boiler room will be redundant for the average user. Therefore, to control solid fuel heating, complexes of two nodes are used: receiving commands presented by a GSM receiver or Internet router, as well as a software and computer complex that is configured once, and then provides the correct interpretation of the commands.

An additional complexity is introduced by the variety of actuators. To control valves and gates, servo drives are used, the performance of smoke exhausters and blowers and circulation pumps usually controlled by a frequency converter or PWM. The complex architecture of the system makes it necessary to order not individual automation modules, but a complete set of equipment. However, most suppliers of such systems provide this kind of service at a very reasonable price: typical projects are about 30-40 thousand rubles, including the cost of equipment, but automation of an atypical boiler house with automatic fuel supply can cost more than 50 thousand rubles with a power of up to 100 kW.

Special Features

As a result, we will analyze which functions of dispatching systems are strictly required, what is the logic of the operation of such devices, and what additional features exist. So, when choosing automation with remote control, preference should be given to those products that provide the following functions:

availability of a backup communication channel;
watchdog timer that reboots the system when it freezes;
interrogation of separate control zones;
remote management of contact groups and their sufficient number;
notification of a change in system status;
feedback, sending messages about the acceptance and execution of commands.

Additional capabilities of the dispatching module must be determined in accordance with the characteristics of the heating system device. So, for liquid heating systems, it is recommended to have leakage protection: humidity sensors and an electronic pressure gauge capable of recording a prolonged pressure drop. For open heating systems, it is desirable to control the liquid level in the expansion tank.

Particular attention should be paid to monitoring the operation of forced circulation devices. If the boiler is technically unable to turn off the heating when the critical temperature is reached, the only indication of overheating can be the temperature sensor readings on the supply pipe, which the control unit receives with a significant delay. In such cases, it is necessary to remotely stop heating by cutting off the supply of fuel or air, and if there is a risk of freezing of the coolant, drain it.

For remote control systems, it is preferable to have an automatic response to abnormal sensor readings. For example, automation itself should adjust the circulation rate depending on the temperature of the coolant in the supply and return, while the user should only receive notifications of critical conditions. In general, we can say that the most important benefit of using the systems we have considered is the timely receipt of information about breakdowns, which allows not only to take personal part in eliminating the accident as quickly as possible, but also to purchase replacements for faulty components or call a specialist if necessary.

Quite often a situation arises when it is necessary to organize temperature monitoring. This can be useful for remote objects: greenhouses, warehouses, cellars, etc.

To solve such problems, there are many on the market various solutions from serious industrial to household. We will not consider the first ones, because they are difficult to implement, expensive, and redundant for everyday tasks. Simpler solutions either use outdated and not perfect in terms of security technology for data transmission via SMS, or are quite expensive, not convenient, and, most importantly, have paid web services.

Therefore, we created our own project, thanks to which each of you will be able to organize remote temperature monitoring.

Our solution is budget-friendly and consists of two components:

Constructor kit for creating a transmitting device
Free web service for remote temperature control and management

Construction kit «LS Monitoring»

The LS Monitoring kit is based on the Arduino platform, which makes it easy to learn.

Generally speaking, a constructor can be used to make a system remote control any object, supplementing it with the necessary sensors. To do this, we released .

But the teaching example in these lessons is the creation of a remote temperature control system.

Although the designer and pursues educational purposes, a device for transmitting temperature can be assembled from it simply by following the instructions, without going into theoretical details.

You can also connect a heater (for example, an electric oven) or a cooler (for example, a fan) to the resulting device, so that you can not only view the temperature, but also influence it remotely.

It is very simple, because when assembling the constructor, you do not need to solder anything! Everything is assembled using special connectors and wires for prototyping.

Web application for remote temperature control "LS Cloud"

The second component of the temperature monitoring system is a web application.

Our LS Cloud app is free and doesn't have to be used with our building kit.

If you yourself are able to develop a device for transmitting temperature, you can use the capabilities of LS Cloud as a web interface for viewing data. You can read about how to transfer data to our service.

LS Cloud has the following features:

Adding an unlimited number of devices

Setting 4 alarm temperature thresholds

The device can be assigned upper and lower warning and alarm temperature thresholds

Notification of the user by Email and SMS when the temperature passes through the set thresholds and the device crashes

When the temperature exceeds the set limits, the system generates warning and alarm messages and sends them to the user via SMS and Email.

Remote device management

As already mentioned, the device assembled from our construction set has a relay for connecting any device (for example, a heater or, conversely, a cooler) to maintain the temperature within the required limits.

Through the LS Cloud application, you can remotely turn on or turn off this device.

Displaying temperature on a graph for a selected period of time

LS Cloud provides storage of temperature data over a long period of time. Based on this data, the application builds a graph.

The user can arbitrarily scale the graph and view the temperature for any period of time.

Tracking the state of communication with a remote device and notifying the user in case of a break

Communication status is displayed as an antenna in front of each device

and in the device data view area on the right side of the screen

In the device settings, you can set the timeout — the time during which the device must be guaranteed to contact the server.

For example, our device “knocks” on the server every three seconds. We set a timeout of 10 seconds. If during this time the device never got in touch, then something terrible happened to it.

If the signal level is weak, you can increase the timeout time.

If the timeout is exceeded, the system notifies the user about the disconnection with the device.

Logging events on the server

The application automatically keeps a log of all events and accidents in the system.

You can get acquainted with the LS Cloud web application at. The password and login for access to the test account are indicated on the main page of the application.

You can order the "LS Monitoring" construction set.

Do you own a country house and are you interested in effective temperature control? It turns out that nowadays there are several more or less effective ways, thanks to which the temperature in the country can be controlled.

The ability to control the temperature in a country house guarantees a number of significant advantages, which we will discuss in this article. And, of course, we will consider the most relevant technologies to date to achieve such results.

What is the purpose of remote temperature control systems?

By installing special equipment, through which the temperature for giving will be regulated, it will be possible to achieve the following results:

Ensuring comfortable parameters of moisture content in the air (moisture content is the ratio of temperature and humidity in the room).
Ensuring a longer service life of a construction object.
It's no secret that sudden changes in temperature and excessive humidity in the cold season is the primary reason for the frequent cosmetic and restoration repairs. Operational adjustment of temperature indicators allows you to prevent the appearance of mold on the walls and extend the service life without the need for repair work.
Ensuring the rational use of energy resources and, as a result, saving money.
In order to ensure optimal parameters of moisture content in the air, you can install a gas boiler or an electric heater and operate them without interruption during the entire cold season. But, in the end, the bill for consumed electricity or gas will be impressive.
You can do otherwise and apply a system in a country house that will turn on air heating exactly when it is needed. As a result, energy consumption will decrease significantly, which will save a certain amount of money.
Ensuring the safety of the operation of the construction site.
As already mentioned, you can apply continuous round-the-clock heating, even when you are not at home. But, on the one hand, it is not cheap, and on the other hand, it is unsafe, since heating equipment operated in the absence of a person can be a potential hazard.
The situation is quite different when you receive reliable data on the temperature in the room at a distance and, if necessary, you can adjust this data upward or downward.

So now we know the benefits of remote temperature control. It remains to consider the technologies on the basis of which this control is carried out.

GSM based technologies

To ensure effective control of the temperature parameters of the air in the room, you can use a GSM thermometer for summer cottages and special temperature sensors. The use of such technology is a relatively new development, which is becoming more widespread both in our country and abroad.

Using modern GSM systems, you can not only receive real information about the temperature in the room, but also remotely control these parameters, bringing them to the required value.

The functioning of the remote control system is carried out as follows:

The user of the system, by means of an SMS message via a GSM cellular communication channel, receives information about the values of the controlled parameters and, if necessary, sends a control command by means of a message.
The system, consisting of GSM thermometers and alarm sensors, sets the optimal temperature parameters from the user's point of view and maintains them for the entire specified time.

Remote temperature control is a progressive technology that is actively used in modern systems"Smart House".

Important: A prerequisite for the effective functioning of the GSM thermometer is a stable supply of electricity.
If the power supply is intermittent, you will need to purchase or rent a diesel generator to give.

At the moment, the following versions of GSM-thermometers are presented on the market:

modifications with an integrated thermal converter;
modifications with an external location of the thermal converter.

How GSM - thermometer works

The device is powered by an external or integrated battery. Thus, the device effectively functions until the moment when the battery is discharged. After that, the battery automatically starts charging through the power supply.
Setting the device parameters is done by hand using a PC via a USB connector.
Depending on the brand and model of the device, it is possible to work with one or another number of phone numbers required to send messages.
Phone numbers from which sensor configuration is allowed are determined both when configuring using a PC and when configuring from a phone.
Depending on the modification and model, the device may have a power saving mode., in which the device operates from the internal battery for more than a month.
GSM - the thermometer is supplied to the user with a specialized software which simplifies the use of the system.

Features of the use of remote thermostats

Thermostats of this type are installed at a certain distance from the heating equipment. The required temperature is set on the thermostat, and the heating device starts to work in such a mode that the set parameters are constant with minimal deviations.

In the photo - a stylish thermostat that will decorate any room

The thermostat is controlled by means of keys that duplicate the controls on the heating device. The device is equipped with a digital display, which displays readings about the air temperature in the room.

The advantage of this solution is that the price of a remote thermostat is an order of magnitude more affordable than the cost of a GSM thermometer. At the same time, using the thermostat, you can set the operating parameters of the heating equipment for several days in advance.

A significant disadvantage of such devices is the impossibility of notifying the user at a distance about malfunctions and malfunctions in the operation of heating equipment.

Important: The use of a special thermostat allows you to ensure optimal temperature parameters within a single room or several adjacent rooms.
At the same time, energy consumption becomes more economical, and the resource of heating equipment is longer.

Fortunately, nowadays everyone can remotely control the temperature in a country house. The company offers the most modern and efficient solutions for temperature control during the winter months using remote control.

What tasks should a remote temperature control system perform?

As a rule, the heating control system has two tasks:

1. Maintaining the required temperature in the house. At a minimum, it should ensure that the building itself and the heating system in it do not freeze.
2. Remote switching on of heating in the country or in a smart home. For example, before the arrival of the owners, so that by the time of arrival all the rooms have warmed up to the desired temperature.

To solve the designated tasks, the temperature control system must meet the following requirements:

1. Provide information about the current temperature in the house and outside.
2. Send out alarms if the temperature is out of range.
3. Have remote control, in particular, the ability to regulate the temperature in separate rooms or in the entire smart home in any convenient way (using a mobile application, via SMS messages, etc.).
4. Opportunity self setting and installations.

Ways to control the temperature in the country in winter

There are two ways:

1. If the cottage has Internet access with a Wi-Fi router. In this case, you just need to purchase a GSM system that works via Wi-Fi. You can receive information about the temperature and control it through a program on a PC or a mobile application on a smartphone.
2. If there is no WI-FI in the country house. In this situation, the way out will be to use a regular SIM card in a GSM system. There are a large number of manufacturers of this equipment on the market, and our company is ready to offer you the best options available.

What is a GSM thermostat?

The basic device of the GSM system is to which you can connect various sensors (water leaks, gas leaks, smoke detectors, and others), including.

Modern GSM-thermostats, improved with additional software functions, equipped with relays, are equipment for full-fledged control of the temperature of heating boilers.

How does a GSM thermostat work?

The program underlying the operation of the GSM thermostat allows you to:

1. Set temperature thresholds (lower and upper) and receive SMS messages or voice alerts via an incoming call if the temperature has gone beyond these values.
2. Call the control module and receive voice information about the temperature from each thermometer connected to the unit, or send SMS commands and receive information about the temperature in the country house in the form of SMS messages.
3. Program the notification function: for example, to receive an SMS message with information about the temperature in the smart home and beyond several times a day at a certain time.
4. Set a certain temperature in the interior of the house and change it by calling or SMS at the right time for you (for example, half an hour before your arrival at the dacha).

The principle of operation of all GSM thermostats is the same. Only parts (controller and microcircuits) can differ depending on the manufacturer. We can connect the functions of water leakage, security with video and photo fixation for minimal money. Subsequently, it will be possible to extend the functionality as needed (constructor principle).

What is a modular control system?

The technical component of the GSM thermostat operation is provided by a modular system, since there can be quite a lot of external controlled devices (modules): a heating boiler, electric heaters, security alarm etc.

In fact, the GSM heating control system is a specialized controller, correlated with external sensors and having the ability to change the operating modes of the heating boiler.

The GS-module for temperature control can operate in four modes:

1. Manual. When the system is controlled by SMS messages or calls, with the help of which the user sets one or another temperature regime.
2. Automatic. When, according to signals from external sensors, the controller maintains the temperature conditions set by the user. At the same time, you can change the settings for automatic mode at any time.
3. Control mode. When the system sends SMS messages to the user with alarms: smoke, gas leakage, critical temperature values, etc.
4. Mode according to the schedule for the week. With the ability to set the temperature at certain hours and certain days of the week.

Which GSM module to choose?

The main selection criterion is that the module must perform the functions you need:

simultaneously support the required number of temperature sensors (three, five, ten - your choice);
to communicate through calls or SMS messages (as it suits you);
optimally approach your model of the boiler (our experts will help to sort out this problem).

The main advantages of GSM heating control systems:

round-the-clock and effective temperature control in a smart home or cottage;
convenient remote control through a mobile application or via SMS messages;
expandability through additional modules;
ease of setup and installation;
low cost;
no subscription fee.

Indoor air refers to electronic measuring devices that automate the process of monitoring and controlling the temperature regime of rooms.

They are included in the structure of the heating system of a house, a bathhouse, a garage, a swimming pool, warehouses or air conditioning systems.

Their presence will allow you to remotely control the temperature regime of the internal environment and, if necessary, regulate it.

What are GSM thermometers used for?

GSM temperature sensor is a measuring device that supports notification of the current temperature and control of executive systems.

A thermometer with a GSM transmitter will inform the owner about the temperature regime at the facility.

Based on these data, a decision will be made to increase / decrease the supply of coolant to the house. For example, using GSM thermometers Warm house 11, you can remotely set the optimal temperature regime for yourself in the house.

In addition, devices of this kind can be included in systems fire safety. If the temperature goes beyond the maximum allowed limit, the sensor will send a warning message to the owner's cell phone, as well as set off an alarm, turn off the heating, activate the fire extinguishing system, or perform another action for which it is programmed during the setup process.

How the GSM sensor works

GSM temperature sensors are composed of two modules - measuring, sensor and transmitting GSM-module.

The work of this kind of electronic thermometers is that they measure the temperature and compare it with the limit value (minimum or maximum) that was set in the settings.

If there is a deviation from the permissible value, a message will be transmitted via GSM-communication or a signal will be generated to the actuator.

The alarm signal is transmitted by cellular communication, depending on the specific settings.

This procedure is implemented:

when going beyond the established range;
in case of a sharp increase in temperature, which is typical for a fire;
periodically, at a configurable interval;
upon request from a telephone number linked to the GSM sensor.

Depending on the design solution, electronic thermometers can control parameters in one zone, as does the Teply Dom 11 GSM thermometer, or in different areas. This function is available in the Teply Dom 22 GSM thermometer, which has two sensors with independently adjustable channels.

Rating of the most popular GSM temperature sensors

Below is information about the five most used electronic sensors with a built-in GSM module.

GSM sensor Polus Thermo

The device is an electronic thermometer that measures the temperature in the room and compares it with the programmed upper and lower thresholds.

When one of the specified values is reached, an alarm is sent to the host's telephone number. In total, you can bind up to 6 numbers to which alarm SMS and calls will be sent.

The temperature sensor-GSM has a built-in sensor that can operate in the range of 0…+50ºС. For measurements in a wider range, an external temperature sensor is connected with a measuring interval of -40ºС ... + 99ºС.

To send messages and calls, a GSM module is used that supports GSM-800/900/1800/1900 standards. The alarm transmission time is 20 to 40 seconds.

Alonio T2 GSM is used to control the air temperature in the house and the presence of electricity in the network that feeds the equipment of boiler rooms, air conditioning systems.

If it drops below the set threshold, then the heating system may have broken down, about which a message will be sent to the owner's cell phone.

An increase in temperature will indicate overheating and possible malfunctions of the air conditioning system, which will also be informed.

An external measuring temperature sensor can be connected to the thermometer, which will allow you to control its value in the range of -55ºС ... + 125ºС.

The built-in transmitter for sending messages uses the GSM band 0.85, 0.9, 1.8 and 1.9 GHz. Mailing about the deviation of the set parameters and the absence of voltage can be carried out to 4 numbers.

This is an electronic meter for remote temperature control, including a GSM module and two sensors - built-in and remote.

The device allows you to continuously monitor the temperature regime at two points via two independent channels and send warning messages if it goes beyond the set limits.

If necessary, the current temperature value in the house can be found by sending a service SMS to the temperature sensor.

The used sensor is sensitive to the temperature range from -10ºС to +50ºС (internal) and -55ºС…+125ºС (external). The module uses the following cellular communication standards to transmit alarm signals: GSM 2G 0.85, 0.9, 1.80 and 1.90 GHz.

ALFA - TEMPERATURE

This device is used to control temperature regime on objects with an accuracy of ±0.5ºС.

Humidity measurement is also supported, which will allow you to control the main parameters of the microclimate of the internal environment.

An electronic thermometer is implemented as a controller with a measuring unit, the signal from which is processed according to a programmed algorithm and, if it goes beyond the limit values, an alarm message is sent to the owner.

Information can be transmitted via GPRS or GSM channel to mobile phone, to the cloud, to the server.

This GSM thermal sensor supports measurements in the range from -55ºС to +125ºС. For data transmission, 4 GSM frequencies can be used: 0.85 / 0.9 / 1.8 or 1.9 GHz.

An electronic thermometer with a built-in battery that monitors the ambient temperature and the presence of voltage in the network.

Thanks to the use of an autonomous battery, the device will be able to perform its functions even if the main power supply is turned off.

Battery life is up to 2 days.

If the measured parameters differ from the programmed settings, the device will report this using an alarm message sent by the built-in GSM module. For its operation, frequencies of 0.85, 0.9, 1.8 and 1.9 GHz are used. Newsletter is possible to 4 linked numbers.

Measurements are carried out by two sensors. The built-in one can operate in the range from -10ºС to +50ºС, and the external one - in the range of values from -55ºС to +125ºС.

Conclusion

The use of temperature GSM sensors simplifies the process of controlling the microclimate inside the premises when no one is at home.

Thanks to measuring instruments with a GSM transmitter, you can find out about the temperature discrepancy with the set values in any place where there is only mobile coverage.

The availability of reliable data on the parameters of the microclimate of the internal environment will allow the user to quickly accept correct solution, in order to exclude emergencies and the consequences associated with the failure of heating equipment, air conditioning systems.
