SOLAR RADIATION SENSOR
id074000004500
Purpose/Function
• The solar radiation sensor converts the detected solar radiation amount to an electric signal.
Structure/Construction
• A photodiode (light receiving diode) has been adopted for the solar radiation sensor.
• The solar radiation sensor is located on 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
