Temperature Controller Thermal Sensor, It starts automatically according to the temperature of the motor. The design inspiration comes from the computer CPUs automatic cooling fan. The thermal sensor will accurately detect rising temperature, when the motor is up to 40°, the cooling fan will automatically turn on to cool the motor.

Instructions The sensing range of the thermal sensor is 3-5 cm, so, the thermal sensor does not need to be too close to the motor to detect the motor temperature(Of course, the closer it is, the better the effect), the rc cooling fan will automatic start when the motor is over 40°, it can reduce battery power consumption.
