Among these sensors, thermocouples and RTDs can be mentioned, which have the ability to sense the temperature value. Now, in order for the user to be able to read the temperature of this sensor, he can use thermostats. In fact, one of the most important features of the thermostat is the ability to display the temperature value of the sensor.\r\n\r\nThermostat is a combination of the Greek words Thermo (heat) and statos (stop and stay). Therefore, from the integration of these two words, we understand that the thermostat is a device that maintains the heat at the set point.\r\n\r\nIn addition to displaying the temperature value, thermostats have other functions. Thermostats can keep the temperature of an environment constant. Some thermostats can have more than one temperature sensor connected to them to display the temperature. PLCs also have the ability to read and display the temperature value. But since it may not be economically justified to use PLCs in many cases, thermostats can be used. Some thermostats also have the ability to be networked in industrial processes. They can read several alarms from them. Thermostats are also available
