Product Description
This PAR sensor can be used alone for outdoor monitoring of radiation driving photosynthesis, or it can be used with a fixed weather station. Get accurate and cost-effective measurements of photosynthetically active radiation (PAR) from all light sources used to grow plants.
Product Features
The PAR (photosynthetically active radiation) sensor adopts the principle of photoelectric induction. The par sensor working principle: when there is 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. This par sensor uses high-precision photoelectric sensing elements, with high absorption in the 400-700nm spectral range and good stability. The shell adopts special treatment to reduce dust adsorption and effectively prevent the external environment from damaging the internal components. It is widely used in the research of meteorology, agriculture, air pollution, and other fields.
