Gravity: Tipping Bucket Rainfall Sensor - I2C & UART

This DFRobot rainfall sensor is a highly reliable and user - friendly tool for measuring rainfall. It operates on the tipping bucket principle, providing rainfall values in millimeters and system operating time. With no internal electronic components and a hollow bottom design for automatic rainwater drainage, it offers enhanced stability and sensitivity. It supports both I2C and UART data outputs and is compatible with popular platforms like micro:bit, Arduino, ESP32, and Raspberry Pi. Integrated with the Gravity interface and accompanied by ready - to - use libraries, it's a breeze to set up a rain monitoring system. This sensor is ideal for weather stations, environmental monitoring stations, and smart farms. A tipping bucket rainfall sensor is a common precipitation monitoring device in meteorology. Rainwater enters the collection container through the top inlet, flows into the tipping bucket via a funnel, and when a certain amount accumulates, the bucket tips, generating a pulse signal. The controller then calculates the rainfall by counting these signals. Note that the signal adapter board is not waterproof, so keep it out of the rain. Key features include millimeter - based rainfall measurement, no internal electronics, automatic drainage, multiple data output support, wide platform compatibility, Gravity interface integration, and easy - setup libraries. Applications range from weather and environmental monitoring to smart farming and research/education.

Using this rainfall sensor is quite simple. First, install it in a proper location where it can collect rainwater effectively. Connect it to your preferred platform like micro:bit, Arduino, ESP32, or Raspberry Pi using the provided Gravity - 4P I2C/UART Sensor Connector. Then, use the ready - to - use libraries to set up your rain monitoring system. When it rains, the sensor will start collecting data and provide you with rainfall values in millimeters and system operating time. Remember, the signal adapter board is not waterproof. So, make sure to keep it away from rain to avoid any damage. For maintenance, you don't need to worry much about internal electronic components as there aren't any. However, you should regularly check the hollow bottom to ensure it's not blocked so that rainwater can drain automatically. Also, check the connections to make sure they are secure. This way, your sensor will keep working well and providing accurate rainfall data for a long time.
