This paper expounds the design of a micro weather station system with real-time data collection,short-term weather information prediction and cloud collaborative computing.The system uses STM32 microcontroller as the main control unit to drive the weather sensor to collect data and upload the weather data to the cloud server through 4G mobile communication technology;in the system algorithm design,a plain Bayesian prediction model is used for basic weather forecasting.In the meantime,based on the meteorological historical data of the prediction area,a BP neural network prediction model is established to integrate and modify the basic prediction results.The system prediction results and the actual measured value error is reduced,and the forecast accuracy is relatively improved by 65.14%.
