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.

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.

Using a Thermistor Clearly for this temperature switch relay circuit to work we require some sort of electronic sensor whose characteristics change with temperature. You will find a couple of primary types of components that exhibit ideal temperature sensing qualities: semiconductor junctions and thermistors.

The working of this circuit is simple. It is operating at 9 volts. Initially, when there is no heat the circuit will remain turned off. When the thermistor receives heat its resistance will be decreased and it will let the current flow. This will activate both the transistors and the voltage will be passed to LED and it will light up.
