Kia Cadenza: Air Conditioning System / Photo Sensor Description and Operation
1. |
The photo sensor is located at the center of defrost nozzle. |
2. |
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. |
