Sunlight has a tremendous impact on the lifecycle of almost all creatures on this planet.  humans, animals, and plants all rely on the sun and its radiations. For plants, especially, light is a key factor in photosynthesis reaction and controls their survival. The industrial-grade PAR sensor featuring high performance, accuracy, and easy-installment, is designed to measure real-time photosynthetic light levels, which is the primary driver of plant photosynthesis. This instrument is able to monitor the PAR in environments with natural light sources across a radiation range from 400 to 700 nm and provides important parameters for researchers and farmers. The sensor contains a Silicon photodetector. When there's light in, the sensor generates a voltage signal that is directly proportional to the PAR under the light source. You are able to obtain the measurement value in a unit of μmol/m2•s. The instrument supports the MODBUS-RTU RS485 protocol. You can therefore directly connect this PAR sensor with RS485 data loggers or digital voltmeters to create monitoring systems that meet your own demand.

Note:

  • S-PAR-02A: supporting MODBUS-RTU RS485 protocol, the cable comes in the format of hook-up wires 
  • S-PAR-02B: supporting MODBUS-RTU RS485 protocol, the cable comes in the format of a waterproof aviation connector. With this version, you won't have to use screws to connect the cable to the data logger. And it can be used with SenseCAP Sensor Hub 4G Data Logger instantly with ease.
