Working explanation. when the 10k ntc thermistor senses heat its resistance will be decreased and it will power the circuit. a 10k variable resistor is used to set the circuit to activate the dc fan at your desired temperature. when the ic lm741 receives the input signal it turns on the transistor which amplifies the signal and turns on the fan. Working of automatic temperature controlled fan using thermistor. it works on the principle of thermistor. in this circuit, pin 3 (non inverting terminal of op amp 741) is connected with the potentiometer and pin 2 (inverting terminal) is connected in between of r2 and rt1 (thermistor) which is making a voltage divider circuit.
