Seeed RG-15 Optical Rain Gauge Rain Sensor

The Seeed Industrial-Grade Optical Rain Gauge RG-15 measures rainfall volume and intensity accurately and reliably. It features easy installation and is maintenance-free, suitable for multiple applications that require rainfall data monitoring. It can also be used with Milesight IoT Controllers Such as the UC501 to easily connect with the local LoRaWAN network, enjoying the benefits of low-power and long-range communication.

The Hydreon RG-15 Optical Rain Gauge is a rainfall measuring device intended to replace conventional tipping buckets. It uses beams of infrared light within a plastic lens about the size of a tennis ball. The round surface of the lens discourages collection of debris, and the RG-15 has no moving parts to stick, and no water-pathways to clog. The device features an open-collector output that emulates a conventional tipping bucket, as well as serial communications that provide more detailed data and allow for configuration of the device

The RG-15 may be configured through the serial port, or optionally via DIP switches. The device is lower power to begin with, and enters micropower mode in the absence of rain. Thus, the RG-15 is well suited to solar-powered applications.
