Rain Sensor

Rainwater enters the collector cone and passes through a debris-filtering screen to remove contaminants. It then gathers in one chamber of a tipping bucket mechanism. When the chamber collects exactly 0.2 mm of rain, it tips, triggering a switch and positioning the second chamber. The system ensures accurate measurement and efficient drainage through screened outlets. Constructed from UV-resistant plastic, the device withstands harsh weather. The tipping bucket pivots on low-friction bearings to reduce wear. Stainless steel screws allow easy calibration, while predrilled mounting holes and a built-in leveling trough ensure straightforward and balanced installation for long-term, reliable performance.
