The Gravity: Tipping Bucket Rainfall Sensor is a high-precision sensor designed for accurate rainfall monitoring in weather stations, environmental systems, and smart agriculture. Based on the tipping bucket principle, it delivers rainfall measurements in millimeters and system operating time through I2C or UART outputs.
Unlike conventional sensors, this sensor contains no electronic components inside, ensuring long-term durability and excellent performance. Its hollow bottom design allows automatic drainage of rainwater, improving stability and response sensitivity.
