Plants use energy in the region of the electromagnetic spectrum from 400 -700 nm for photosynthesis. The radiation in this range is referred to as Photosynthetically Active Radiation (PAR).

Solar radiation sensors measure solar energy and provide outputs corresponding to the level of radiation being monitored. Combined with a display or control device, the user can receive an alert when solar intensity reaches a predetermined threshold level. This can be useful for controlling solar powered equipment and systems such as solar lighting and solar panels.

Solar Radiation Sensors are commonly used in climatology, meteorology, building physics and solar energy studies. They are also used in weather stations and are often installed in a horizontal manner near solar panels.

Experts in the fields of meteorology, building physics, climatology, and solar energy generally rely on state-of-the-art solar sensors the most. However, these sensors also aid weather stations.
