SOLAR RADIATION SENSOR [FULL-AUTO AIR CONDITIONER]
Purpose, Function
The solar radiation sensor converts the detected solar radiation amount to an electric signal.
Construction
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.
