Overview
The Hydreon RG-11 Rain Gauge is a maintenance-free optical rain sensor that can be used for a wide variety of rainfall monitoring and control applications. The Rain Gauge senses water hitting its outside surface using beams of infrared light, which is the same sensing principle used in millions of automotive rain sensing windshield wiper controls. The complete sensor package is about the size of a tennis ball and completely sealed from the environment.

Design
The optical sensing technology overcomes many of the shortcomings of conventional tipping bucket rain gauges. The sensor works in mobile environments, there is no collecting funnel to clog with leaves, and the round shape makes it essentially self-cleaning.

Modes
The Hydreon RG-11 includes a DIP switch that allows it to be set for the mode of operation that best matches the application.

  • Tipping Bucket: Emulates a tipping bucket of the specified size
  • It's Raining: Turns on the relay to indicate that it is raining when the rainfall has reached a given intensity
  • Condensation Sensor: Detects condensation or frost formation on the surface
  • Wiper Control: Rain sensing wiper control at various speeds
  • Irrigation Control: Rain Gauge output to inhibit watering
  • Drop Detection: Produces a pulse for each drop detected

 

Questions & Answers
How does the Rain Gauge sense condensation?
Generally the RG-11 will sense condensation as if it were rainfall, but this seldom amounts to a significant accumulation of water. The built-in low power heater (DIP SW 8 off) will tend to reduce condensation. If condensation or frost measurements are desired, the rain gauge can be set to high sensitivity to detect slight shifts to and from "clear" conditions.
Can bright sunlight damage the optical rain gauge?
The RG-11 is almost completely immune to the effects of ambient light, and may freely be mounted in direct sunlight.
