If a Thermistor is connected in a circuit that switches a relay like the circuit below it is called a Thermistor relay. The transistor changes state and switches a relay coil (the load in the circuit below) to operate something like a fan or to shut a device off if the temperature increases too much..

Dec 21, · The relay is configured by using a small Driver circuit which consists a Transistor, Diode and a resistor. Transistor is used to amplify the current so that full current (from the DC source – 9v battery) can flow through a coil to fully energies it. The resistor is used to provide biasing to the transistor.

In this type of circuit, the thermistor would be in an ambient self-heated condition. The ther- mistor’s resistance is changed by the amount of heat generated by the power dissipated by the element. Any change in the flow of the liquid or gas across the device changes the power dissipation factor of the thermistor element.

The temperature sensor circuit using a thermistor exploits the property of a sensor to operate the fan or any other device. This circuit also controls the temperature of any device according to the requirement of an industry. The main idea of a temperature sensor circuit is to control the speed of a fan by heating a thermistor.

The word thermistor is a portmanteau of thermal and resistor. Thermistors are divided based on their conduction model. Negative Temperature Coefficient (NTC) thermistors have less resistance at higher temperatures, while Positive Temperature Coefficient (PTC) thermistors have more resistance at higher temperatures.
