The Hydreon RG-11 Solid State 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.

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.

But don’t worry about the complexity of the Optical Solid State Rain Sensors. Think of them as a functional block that detects and communicates the rain sensing function for you– reliably, low maintenance, and at a low cost.

The Hydreon RG-9 Solid State Rain Sensor is a rainfall sensing device intended to detect and communicate when a pre-selected rain intensity has been reached or exceeded. The RG-9 is rugged, reliable, and maintenance-free.

The RG-15 is designed to replace tipping bucket rain gauges in many applications where their maintenance requirements make them impractical. The RG-15 uses beams of infrared light within a plastic lens about the size of a tennis ball.

OPTICAL RAIN GAUGE MODEL RG-11 INSTALLING THE RAIN SENSOR 1. Determine the Mode / Set DIP switches You must set the DIP switches so that the RG-11 behaves the right way for your application. The pages that follow describe each of the possible modes, and how to set the DIP switches. 2. Mount the Rain Gauge Mount the rain Gauge where it gets a clear

Hydreon has a Rain Gauge suitable for almost any application that requires a reliable and sensitive rain sensor. The physical dimensions for each model is the same: Length: 4.8″ (121 mm) Width: 2.8″ (71 mm) Height: 2.2″ (56 mm) Weight: 4.3 oz (122 g)
