Hydreon RG-11 Optical Rain Sensor with 6 Digit Counter

Hydreon RG-11 Optical Rain Sensor with 6 Digit Counter

We have combined the Hydreon RG-11 Optical Rain Sensor with a Novus 6 Digit Counter. With the RG-11 operating in the tipping rain bucket mode the counter will display the amount of rain that has fallen since the last reset. A modbus RS-485 interface on the counter allows a PLC or SCADA host to communicate with the counter to access rain data.

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.

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 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

Please note: The RG-11 can't be powered with 5 V via the 5 V pin on the header as it won't be able to boost its emitter current with just 5 V. Please power the device with minimum 12 V through the main terminal block
