Photosynthetically active radiation sensor

Also known as light quantum number, it 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 a data collector, and can be used under all-weather conditions.

The watch uses a silicon photodetector and passes through a 400-700nm optical filter. When illuminated by 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
