The BGT-PAR photosynthetically active radiation sensor, also known as the photon quantum number, is mainly used to measure the photosynthetically active radiation of natural light in the wavelength range of 400 to 700 nm, and is simple to use, and can be directly connected to a digital voltmeter or a data collector, and can be used under all weather conditions.
The meter uses a silicon photodetector and passes through a 400-700 nm optical filter. When illuminated by light, a voltage signal proportional to the intensity of the incident radiation is generated, and its sensitivity is proportional to the cosine of the direct angle of the incident light. Each photosynthetic active radiation meter gives its own sensitivity and can be read directly. The unit is μmol/m2·s. This table is widely used in agricultural meteorology and crop growth research.
