Quantum PAR Sensor, Photosynthetic Active Radiation Sensor

The SX2594 PAR Sensor is mainly used for measuring solar radiation within
400~700nm wavelength. 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-photo detector 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.
