SOLAR RADIATION SENSOR [FULL-AUTO AIR CONDITIONER]

Purpose, Function

  • The solar radiation sensor converts the detected solar radiation amount to an electric signal.

Construction

  • A photodiode (light receiving diode) has been adopted for the solar radiation sensor.

  • The solar radiation sensor is located on the driver side of the instrument cluster.

Operation

  • The solar radiation sensor detects the solar radiation amount using the characteristic of the photodiode (light receiving diode) which flows current when the light strikes the semi-conductor part of the photodiode. The generated electrical current increases if the sunlight intensity increases, and decreases if the sunlight intensity decreases.

Fail-safe

  • Not applicable
