Rain Gauge Model RG-11
The RG-11 Rain Gauge 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. Consequently, it is remarkably inexpensive, at just $59 for a single unit.
The RG-11 is optical– not mechanical, chemical, or conductive. Consequently, it is far more rugged, sensitive and reliable than any other technology. The sensor is extremely sensitive, and virtually immune to false trips. Yet, it is completely unaffected by jostling and motion. There are no exposed conductors to corrode, and no openings for bugs to crawl into. There is no place for leaves or other debris to collect.
Applications for the Rain Gauge
The RG-11 Rain Gauge is suitable for almost any application that requires a reliable and sensitive rain sensor, including:
You can use the RG-11 to reliably detect condensation or frost.
The RG-11 Rain Gauge measures both rain accumulation and rain intensity.
The RG-11 may also provide drop detection for your own external data interpretation.
The RG-11 Rain Sensor can be used to control a wiper system on boat, ship, locomotive, and more
RG-11 Modes of Operation
The RG-11 Rain Sensor includes a DIP switch that allows it to be set up for the mode of operation that best matches the application.
Replace your tipping bucket with a low maintenance alternative
Close a skylight at the first sign of rain, and open it when it stops raining
In this mode, the Rain Gauge continuously monitors the clarity of the sensing surface.
This mode will control the wipers from off through intermittent and steady-slow speeds.
This mode will measure both rain accumulation and rain intensity.
Use this mode if you want to do your own external data interpretation.
