The photosynthetically active radiation sensor adopts the principle of photoelectric induction and can be used to measure 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, it generates a voltage signal proportional to the intensity of the incident radiation, and its sensitivity is proportional to the cosine of the direct angle of the incident light. The dust cover adopts special treatment to reduce dust adsorption, effectively prevent environmental factors from interfering with internal components, and can measure photosynthetically active radiation more accurately.
The product adopts the standard Modbus-RTU 485 communication protocol, which can directly read the current photosynthetically active radiation value, and the wiring method is simple. The appearance is small and beautiful, and it occupies a small installation space. The product is widely used in research in meteorology, agriculture, air pollution and other fields.
