DescriptionThe In-car air temperature sensor is built in the heater & A/C control unit.The sensor contains a thermistor which measures the temperature of the inside.
Description The photo sensor is located at the center of the defrost nozzles.The photo sensor contains a photovoltaic (sensitive to sunlight) diode. The solar radiation received by its light receiving portion, generates an electromotive force in proportion to the amount of radiation received which is transferred to the automatic temperature control module so that the solar radiation compensation will be performed.
