Par light sensor

Par light sensor (Photosynthetic Active Radiation Sensor):

Photosynthetic Active Radiation Sensor(PAR Sensor)  also known as the number of light quantum,is mainly used to measure the photosynthetic effective radiation of natural light in the wavelength range from 400 to 700 nm,and it is easy to use, which can be directly connected with digital voltmeters or data collectors and can be used under all-weather conditions.

It is easy installation and can work continuously in all weathers. When there is sunlight, voltage output proportional to incident light intensity will be generated by the Silicon photodetector in the sensor. Its sensitivity is proportional to the cosine of incident light direct angle. Each product is with one sensitivity coefficient respectively.It can directly output radiation value in unit of μ*mol/m2*s.
