Hydreon Optical Rain Sensor - Model RG-11

Use it to measure rainfall, or to close a skylight when it starts raining

The RG-11 Rain Sensor is about the size of a tennis ball, and is completely sealed.

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.

The right rain sensor for YOUR application

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.

RG-11 Modes of Operation

Tipping Bucket Emulation-- Replace your tipping bucket with a low maintenance alternative.
"It's Raining"-- Close a skylight at the first sign of rain, and open it when it stops raining.
Condensation / Frost Sensing
Wiper control
Irrigation Control-- No more watering during a downpour!
Drop Detection

The Rain Gauge circuit board. The DIP switch programs the mode, and connections are made with convenient screw terminals.

Applications

The RG-11 Rain Gauge is suitable for almost any application that requires a reliable and sensitive rain sensor, including:

Automatic control of skylights, windows, and louvers, and awnings.
Condensation sensing in HVAC humidification systems.
Control of wastewater systems, or other systems that require measuring rainfall.
Wiper control for ships, boats, or specialized vehicles and equipment
Refrigeration frost sensing
Sophisticated irrigation control, or as an input to an irrigation control system.
Industrial/process control
Meteorology-- especially low rainfall and mobile applications.
Data gathering.

At last your rain sensing problem is solved, and at a remarkably low cost.

RG-11 Rain Sensor in "It's Raining" Application

This RG-11 Rain Sensor shuts the windows of a building on a campus in Oxnard, CA. This assists with passive cooling, without the worry of water drifting into the building.
