How the Rain Gage Works |
The RG-10 Rain Gage has a clear compound lens that makes up the sensing surface. Beams of invisible, infrared light bounce around inside the lens and off the outside surface. Electronic circuits pulse infrared emitters to generate the beams, and amplify the received beams. Sophisticated software gathers data and interprets it. Digital Signal Processing techniques extract small signals and help get rid of the effects of ambient light disturbances. Other software makes the output appropriate for the application, such as tipping bucket emulation or drop detection.
The RG-10 borrows technology that was developed over many years for automotive rain sensing windshield wiper controls. We can offer the RG-10 at such a righteous price because the development was largely paid for through our research in the automotive field.
But don't worry about the complexity of the Rain Gage. Think of it as a functional block that encapsulates the rain sensing function for you-- reliably, maintenance-free, and at a low cost.

Most of the complexity of the RG-10 is in the software and injection-molded optics. Sophisticated, but inexpensive to produce. (Hover over the Rain Gage parts for brief description)
