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-9 uses beams of infrared light within a plastic lens about the size of a tennis ball. The round surface of the lens discourages the collection of debris, and the RG-9 has no moving parts to stick, and no water-pathways to clog. The device features an open-collector output that indicates when the selected rain intensity has been reached.
The sensitivity levels are:
- Rain Drops,
- Very Light,
- Medium,
- Heavy.
The duration of the positive detection is also selectable:
- No Hold,
- Hold Time 5 Minutes,
- Hold Time 10 Minutes,
- Hold Time 15 Minutes.
The power consumption of the RG-9 is very low, and the device is well-suited to solar-power applications.
![]() The RG-9 sensor does not indicate the amount of waterfall, just rain or dry – so the graphs will show only 2 levels (with an additional 3rd level in case of disconnection of the RG-9). |
