How to make temperature sensor fan circuit | Automatic ON and OFF temperature sensor fan.
Connect All Parts As the Image Above
This circuit uses a thermistor as a sensor, the thermistor resistance decreases when a temperature increases.
When the temperature increases the thermistor resistance decreases until the voltage set point that adjusts by potentiometer higher than Vgs threshold, MOSFET change to ON state and make a 12 volts fan start and rotating speed faster when a temperature hotter.
The capacitor that parallels with a thermistor help fan starts instantly at lowest speed when power on, The 12 volts DC fan makes noise and not rotating without the capacitor (maybe a cheap Chinese power supply cause it).
I set the threshold point at 25 C, the fan starts at lowest speed @ 25 C and rotating fastest @ around 38 C (I touch it and wait a few munites to see the result)
