A humidity sensor, in which the glass temperature sensor, glass surroundings temperature sensor and glass humidity sensor are integrated, is used.
The glass temperature sensor detects the surface temperature of the windshield using the built-in thermistor attached to the back of the sensor board, and outputs the signal to the air conditioning amplifier assembly.
The gases surroundings temperature sensor detects the air temperature near the windshield using the built-in thermistor, and outputs the signal to the air conditioning amplifier assembly.
The glass humidity sensor converts a change in the electrostatic capacity between the electrodes by allowing the humidity-sensing film to absorb and desorb moisture in the cabin, and outputs the signal to the air conditioning amplifier assembly.
