Design of Small Automatic Weather Station Monitoring System Based on NB-IoT Technology

Aiming at the shortcomings of traditional meteorological stations, such as the high complexity of communication technology, high cost of construction, poor timeliness and high power consumption, a small automatic weather station monitoring system based on NB IoT technology is designed. The system is mainly composed of the meteorological sensing equipment, single station controller and IoT (Internet of Things) cloud platform. This system uses the low power Corter M3 core STM32L152 micro control chip as the hardware core, relying on the meteorological sensor equipment to realize the collection and processing of meteorological element data; using NB IoT technology to realize the data transmission between the weather station and the cloud server; utilizing RESTful API and MySQL technology to implement user interaction, remote terminal control and data storage, display, analysis, query and other functions. The test results show that the system has simple construction, low power consumption and stable data transmission. It can realize the remote real time monitoring of meteorological elements.
