Description

The photo sensor is located at the center of the defroster nozzles. The photo sensor contains a photovoltaic cell (photodiode sensitive to sunlight). The solar radiation received by its light-receiving part generates an electromotive force proportional to the amount of radiation received, which is sent to the automatic temperature control module so that solar radiation compensation is performed.
