Optical Rain Gauge – RS485


The Optical Rain Gauge is an electronic sensor that detects water hitting the outer surface of the sensor using beams of infrared light. It uses the same sensing principle used in motor vehicle windshield wiper controls.

The sensor is optical, not mechanical, chemical, or conductive, and it is therefore far more rugged, sensitive and reliable than tipping bucket rain gauge technology. There are no exposed conductors to corrode, no moving parts to wear out, and no openings for bugs to crawl into. The design also prevents debris build-up making this perfect for remote deployments where maintenance would be an issue.      

Accuracy: ±15%

Resolution: 0.1mm

For mounting, you may require a Sensor Mounting Pipe.
