For use with standard versions of GroWeather, Energy EnviroMonitor, or Health EnviroMonitor.

Measures solar radiation. Also required (along with an anemometer and a temperature/humidity sensor) if you wish to monitor evapotranspiration.

Diffuser element and housing are carefully designed for accurate cosine response. Silicon photo diode provides good match to solar spectrum. Two-piece housing minimizes radiation heating, allows convection cooling of the sensor, and prevents the trapping of water or dust. Includes built-in level and 40' (12 m) standard cable.
