In order to meet the needs of modern meteorological detection, automatic weather station of the Internet of Things is developed. Local area wireless sensor networks are composed of temperature, humidity, wind, pressure, precipitation and other meteorological sensor nodes, routers, and the coordinator. Wide area networks are also composed of the data communicator and remote computer through 3G, GPRS and the Internet. Data are received, analyzed and stored to real-time network database by the remote computer after the quality control. Meteorological data management and distribution is implemented and the data can be consulted through the user’s mobile phone or Internet computer.
