A Study of Agricultural Meteorological Monitoring System Based on Wireless Sensor Networks

In order to keep the sustainable development of agricultural industry, monitoring the four basic essential elements’ changes, which are temperature, humidity, light intensity, carbon dioxide, and applying the corresponding solution is really necessary. An agriculture meteorological monitoring system with ZigBee wireless sensor networks（WSNs） and wireless communication technology is designed in this paper. Sensor nodes are distributed in the measurement area and form a self-organizing network. The sink collects information which transmitted from sensor nodes and then, sends the information to the server. Server will summarize the information, then taking analysis and processing. At the end, the server will give some corresponding warning and forecast. The cost of this system is low and could improve the accuracy and timeliness in agricultural meteorological monitoring.
