The Seeedstudio Industrial-Grade Optical Rain Gauge RG-15 Rain Sensor is a perfect fit. It's a reliable, cost-effective, and rugged rain gauge that uses light beams to determine how much rain has fallen at what intensity.
The RG-15 Optical Rain Gauge 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.
It can be configured through the serial port, or optionally via DIP switches. A built-in mounting arm allows for convenient mounting to weather station masts, buildings, and other infrastructure. It's also suitable for solar-powered applications.
