DFRobot Gravity Tipping Bucket Rain Gauge Rainfall Sensor I2C UART compatible with micro:bit Arduino ESP32 Raspberry Pi For weather stations environmental monitoring stations smart farms. Introduction This DFRobot rainfall sensor is a reliable and convenient tool for measuring rainfall. Based on the principle of tipping bucket rainfall, the rainfall sensor provides users with rainfall values in millimeters and system operating time. The sensor has no electronic components inside and features a hollow bottom design that allows rainwater to automatically drain, making it more stable and sensitive. It supports I2C and UART data outputs, compatible with micro:bit, Arduino, ESP32, Raspberry Pi. Integrated with the easy-to-use Gravity interface, this rainfall sensor can be used to set up a rain monitoring system easily with the provided ready-to-go libraries. The tipping bucket rainfall sensor can provide high-quality rainfall data for weather stations, environmental monitoring stations, or smart farms. What is a tipping bucket rainfall sensor? The tipping bucket rainfall sensor is one of the commonly used precipitation monitoring devices in meteorological observations. It consists of a collection container and a measuring mechanism. During rainfall, water enters the collection container through the top inlet and flows into the tipping bucket through a funnel. When a certain amount of water accumulates, the tipping bucket loses its balance and tips over, generating a pulse signal with each tip. By recording the number of pulse signals, the controller can calculate the rainfall amount. Note: The signal adapter board is not waterproof. Do not expose the signal adapter board to rain.
