Seeed PAR Sensor

Description The industrial-grade PAR sensor monitors 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. When there's light in, the sensor generates a voltage signal directly proportional to the PAR under the light source. You can obtain the measurement value in a unit of μmol/m2•s. The instrument supports the MODBUS-RTU RS485 protocol, you also can directly connect this PAR sensor with RS485 data loggers or digital voltmeters to create monitoring systems that meet your own demand. The Industrial PAR Sensor has three versions.      (1) PAR-2.5V: supporting 2.5V analog voltage output, the cable comes in the format of hook-up wires.       (2) S-PAR-02A: supporting MODBUS-RTU RS485 protocol, the cable comes in the format of hook-up wires        (3) S-PAR-02B: supporting MODBUS-RTU RS485 protocol, the cable comes in the format of a waterproof aviation connector.
