240-CSD3 Sunshine Duration Sensor

The 240-CSD3 Sunshine Duration Sensor provides the number of sunshine hours per day. The 240-CSD3 has no moving parts and uses three photo-diodes with specially designed diffusers to make an analog calculation of when it is sunny (direct solar irradiance greater than 120 W/m²). An output is switched high or low to indicate `sunny` or `not sunny` conditions. The calculated direct irradiance value is also available.
