Simple Heat Sensor or Temperature Sensor Circuit Diagram Here Transistor BC547 is used as a Heat Sensor. As the temperature of PN junction increase, transistor starts conducting to some extent. This ‘temperature’ property of transistor is used here to use it as a heat sensor. Diode 1N4148 and variable resister of 1k ohm are used here to set a reference or threshold level for the sensitivity of heat. And the sensitivity of the circuit can be adjusted by rotating the knob.
