Photon sensor is mainly used to measure plant photosynthetic effective radiation (PAR) or photosynthetic photon flux density (PPFD) of natural or artificial light sources in the wavelength range of 400nm-700nm. Its special waterproof design can be used under all-weather conditions. It is widely used in the research of agricultural meteorology or crop growth and ecology.
