Optical Rain Gauge RG-15

This industrial-grade optical rainfall measuring device is intended to replace conventional tipping buckets of rain gauges. It uses beams of infrared light within a plastic lens about the size of a tennis ball. It is maintenance-free: with the round surface of the lens, there are no collections of debris, no moving parts to stick, or water-pathways to clog.

RG-15 Solid State Rain Sensor features an open-collector output that emulates a conventional tipping bucket, as well as RS232 serial communications that provide more detailed data.
