Description

The photo sensor is located in the center of the defroster nozzles. The photo sensor contains a photoelectric diode (sensitive to sunlight). The sun's rays captured by the photo sensor receiver generate an electromotive force proportional to the amount of radiation received, which is transmitted to the automatic temperature control module so that solar radiation compensation is performed.
