The photosynthetically active radiation sensor adopts the photoelectric sensing principle and can be used to measure the photosynthetically active radiation in the spectral range of 400~700nm. The sensor adopts high-precision photoelectric sensing elements, wide spectrum absorption, high absorption in the range of 400-700nm, and good stability; when there is light, a voltage signal proportional to the incident radiation intensity is generated, and its sensitivity is proportional to the incident light. The cosine of the direct angle is proportional. The dust cover adopts special treatment to reduce dust adsorption, effectively prevent environmental factors from interfering with internal components, and can measure the amount of photosynthetically effective radiation more accurately.
