Design of Miniature Automatic Hydrometeorological Station Based on ESP32

This article introduces a miniature automatic hydrometeorological station based on the ESP32 microcontroller, which aims to solve the problems of difficult maintenance and high construction costs associated with traditional weather stations. This station can collect various environmental information, such as water level, rainfall, temperature, humidity, air pressure, wind speed and direction, pH, etc., and can also add other sensors such as light intensity and soil data. Through the OneNET platform of China Mobile's IoT, technologies such as EChart and OneNET View are used to achieve user interaction, data visualization, historical data query and other functions. This weather station is suitable for meteorology, hydrology, agriculture and other fields, and can achieve real-time monitoring of meteorological elements and remote transmission of data, improving the accuracy and refinement level of weather forecasting. Compared with traditional weather stations, this weather station has simple installation, convenient maintenance, strong scalability, and is conducive to the popularization and development of meteorological observation.
