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.\u003c\/p\u003e\n\u003cp\u003eIt 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.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhat is a tipping bucket rainfall sensor? \u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cspan style=\"color: #ff0000;\"\u003eNote:\u003c\/span\u003e\u003c\/b\u003e The signal adapter board is not waterproof.
