Solar Radiation Sensor (Silicon Pyranometer) – S-LIB-M003

The Solar Radiation Smart Sensor is a light sensor (silicon pyranometer) with a measurement range of 0 to 1280 W/m2 over a spectral range of 300 to 1100 nm. This sensor reports the average light intensity over a user-set set logging interval from a minimum of 1 second. Although the azimuth error is only 2% error at 45 from vertical, a light sensor bracket and light sensor level are recommended.

Measurement parameters: average over logging interval, user-defined sampling intervalfrom 1 second.

Note: Light sensor bracket (M-LBA) and light sensor level (M-LLA) recommended
