Solar Radiation Sensors are used to measure the power of the light and heat from the sun. There are two primary types of Solar Radiation Sensors; PAR Sensors and Pyranometers.
(1) PAR Sensors are capable of measuring photosynthetically active radiation (or PAR) within the 400 to 700 nm range.
(2) Pyranometers are comprised of a thermopile sensor that typically has a black coating.
Solar Radiation Sensors are commonly used in climatology, meteorology, building shysics and solar energy studies. They are also used in weather stations and are usually installed in a horizontal manner near solar panels.
