RY-CGH Photosynthetically Active Radiation Factory Price 0-2000mV RS485 4-20mA PAR Sensor For Greenhouse

The RY-CGH photosynthetically active radiation sensor is mainly used to measure the photosynthetically active radiation of natural light in the wavelength range of 400-700nm, and it is easy to use. It can be directly connected with a digital voltmeter or data collector, and can be used under all-weather conditions. The sensor uses silicon photodetector, and through a 400-700nm optical filter, when there is light, it produces a voltage signal which 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. Each photosynthetically active radiometer gives its own sensitivity (when the original millivolt voltage is output), which can be directly calculated in μ· mol / m 2•s
