With the development of society, our requirements for the accuracy and real-time nature of meteorological information collection are also constantly increasing. However, most ground weather station monitoring systems in my country are large in size and have high system power consumption, which results in high construction costs for traditional weather stations and are not suitable for large-scale construction.

The small automatic weather station combines a high-performance micro-control processing chip with a weather sensor to collect and process wind direction, wind speed, temperature and humidity, illumination, PM2.5, PM10 and other meteorological elements in real time, and uses NB-IoT technology to stabilize Transmit system data to achieve remote meteorological data monitoring. In terms of power supply, a 24-hour solar power supply system and a large-capacity battery are used to provide power when the sun is insufficient or at night.

The advantages of small automatic weather stations are high flexibility, low power consumption, low station construction costs, and good signal transmission stability.
