GSM temperature sensors. GSM thermometers and alarms with thermo sensors. Remote temperature sensors How the remote temperature sensor works

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 Teply Dom 11 GSM thermometers, you can remotely set the optimal temperature regime for yourself in the house.

In addition, devices of this kind can be included in fire safety systems. 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:

1. when going beyond the established range;
2. in case of a sharp increase in temperature, which is typical for a fire;
3. periodically, at a configurable interval;
4. 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.

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 a mobile phone, to the cloud, to a 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 devices with a GSM transmitter, you can find out about the discrepancy between the temperature regime and 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 make the right decision in order to eliminate emergency situations and the consequences associated with the failure of heating equipment and air conditioning systems.

Remote temperature sensors are designed to control temperature while being at a distance from controlled objects. The ability to work with remote surfaces provides a wide application of remote temperature sensors.

Types of remote temperature sensors

To solve various problems, stationary and portable remote sensors can be used to determine the temperature. Stationary sensors are fixed at a certain point opposite the controlled object. Portable models can move depending on the placement of the object of control, due to which they are more widely used.

Remote sensors measure surface temperature using infrared radiation. Based on the characteristics of the work, the sensors can have different performance characteristics, including the limits of the measured temperatures and the response time. Sensors are also made from various materials.

Fields of application for remote temperature sensors

Remote temperature sensors are suitable for many industries. The ability to control the temperature of an object without direct contact allows you to replace standard contact sensors in the following areas:

• production of heat and electricity,
• mining and processing of metals,
• oil and gas industry,
• production of machine tools, machines and mechanisms,
• production and repair of vehicles,
• construction industry and maintenance of buildings and structures,
• railway industry,
• food industry,
• storage and transportation of various products.

Also, remote sensors can be used in everyday life to control the temperature of residential buildings and premises with the ability to work within the framework of a “smart home” type system.

Purpose of remote temperature control sensors

The main purpose of remote sensors is to control the temperature of objects without contact with the surface. In addition, sensors can solve other tasks related to temperature measurement:

• temperature measurement up to 3000 o C,
• work in conditions of inaccessibility of objects for contact temperature measurement,
• control of the state of moving elements,
• work with surfaces inaccessible for contact methods of temperature measurement,
• work with objects under voltage,
• temperature measurement of objects made of materials with low thermal conductivity.

Benefits of choosing a remote temperature sensor

Remote temperature sensors compare favorably with other measurement options due to several advantages:

• remote temperature control of hard-to-reach objects,
• temperature measurement of materials inaccessible to contact,
• the ability to measure the temperature of hazardous objects or those operating in hazardous conditions,
• determination of very high temperatures,
• fast results due to short response time,
• increased wear resistance of the sensor due to the absence of contact with the controlled medium,
• ease of operation after the initial setup of the equipment.

Limitations in the use of remote temperature sensors

Since remote temperature sensors are infrared sensors, it is necessary to adjust the sensor to work with different types of materials. This is due to the thermal conductivity of each specific type of object. Based on these features, correction factors should be introduced into the work. The accuracy of the sensor results depends on the correct choice of a specific model for work, as well as on a careful approach to setting up the equipment before work.

The principle of operation of the remote temperature sensor

To determine the temperature of an object, the sensor measures the level of electromagnetic thermal radiation emanating from the control object. Depending on the heating of the object, this radiation can be in the infrared range or in the visible spectrum at very high temperatures. The remote temperature sensor captures the level of radiation and converts it into an outgoing signal. Measurement of temperature by the level of radiation allows measurements in a wide range: from -45 o C to +3000 o C.

To ensure high measurement accuracy, it is necessary to select different models of the sensor for operation in specific conditions, based on the capabilities of the sensor and the characteristics of the controlled object.

Temperature sensors are used as part of burglar alarms or Smart Home systems. Their main function is to control the temperature in the room. You should buy a GSM temperature sensor when it becomes necessary to collect information and send it to the central alarm device. In Smart Home systems, the device allows you to find out information about the indoor climate, which affects the automatic switching on or off of electrical appliances. GSM-control of the premises, an integral part of which is an alarm system with temperature sensors, allows you to save the owner's time and money as efficiently as possible. It is enough to purchase and install a SIM card, and connect the sensor to an electrical outlet.

What are GSM thermometers for?

• For remote control of all types of heating devices (electric, gas or solid fuel boilers);
• To control heaters (air conditioner, infrared heaters, underfloor heating and others);
• To collect information about temperature and humidity.

If you believe the reviews of experts about GSM thermometers and alarms with temperature sensors, then we can conclude that temperature control and regulation systems are the most modern ways to control the room climate. This is not only heating or air conditioning, but also the ability to filter the air and humidify it.

Why is it worth buying a GSM thermometer and an alarm system with temperature sensors?

• Possibility at any time to get all the information about the temperature regime. Most of the models can be controlled through Android/iOS Apps, allowing real-time data collection and use;
• The device can perform dozens of tasks in automatic or semi-automatic modes, eliminating the need for the user to manually control temperature and climate variables;
• The price of a GSM temperature sensor seems to be quite low, considering all the possible ways to save electricity, water, gas, which are achieved by using the device;
• If the temperature reaches a critical point (which you set yourself), the sensor will report this by sending an SMS message. In addition, the device can be configured and controlled using SMS commands.
