{254} Room Temperature Sensor / Pipe or Coil Temperature Sensor (Thermistor) in AC Urdu Hindi

in this video i explained function & testing Room Temperature Sensor / Pipe coil Temperature Sensor thermistor in Split AC. Function Test, i discussed in urdu hindi language. sensor is NTC negative temperature coefficient resistance. its resistance decreases with increase in resistance. this changed resistance value will change the voltage at microcontroller pin, which converts the voltage value into digital data,
