The photosynthetically effective radiation sensor is mainly used to measure the photosynthetically effective radiation of natural light in the wavelength range of 400-700nm, and is simple to use. It 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 400-700nm optical filter. When there is light, a voltage signal is generated that is proportional to the intensity of the incident radiation, and its sensitivity is proportional to the cosine of the direct angle of the incident light. μ • mol / m2 • s.This table is widely used in agricultural meteorology and crop growth research.
