A pyranometer is a type of actinometer used for measuring solar irradiance on a planar surface and it is designed to measure the solar radiation flux density (W/m2) from the hemisphere above within a wavelength range 0.3 I m to 3 I m. The name pyranometer stems from the Greek words I a? I (pyr), meaning "fire", and a I I (ano), meaning "above, sky".
A typical pyranometer does not require any power to operate.

The solar radiation spectrum that reach earth surface extends its wavelength approximately from 300 to 2,800 nm. Depending on the type of pyranometer used, irradiance measurements with different degrees of spectral sensitivity will be obtained.

To make a measurement of irradiance, it is required by definition that the response to a beama radiation varies with the cosine of the angle of incidence. This ensures a full response when the solar radiation hits the sensor perpendicularly (normal to the surface, sun at zenith, 0A angle of incidence), zero response when the sun is at the horizon (90A angle of incidence, 90A zenith angle), and 0.5 at a 60A angle of incidence. It follows that a pyranometer should have a so-called a directional responsea or a cosine responsea close to the ideal cosine characteristic
