The Optical Rain Sensor senses water hitting its outside surface
using beams of infrared light. It uses the same sensing principle
used in millions of automotive rain sensing windshield wiper
controls.
The Sensor is optical-- not mechanical, chemical, or conductive.
Consequently, it is far more rugged, sensitive and reliable than
any other technology. And the sensor is extremely sensitive, and
virtually immune to false trips.In addition, it is completely
unaffected by jostling and motion. There are no exposed conductors
to corrode, and no openings for bugs to crawl into. And there is no
place for leaves or other debris to collect.Optical rain sensor digital rain gauge for roof system
