Wireless sensor networks(WSN) is a very active research topic which already has been used for environmental monitoring, public safety, medicine, and military. This paper introduces a practical type of WSN used for ground verification of remote sensing. This WSN mainly consists of sensor nodes, convergent nodes and data-processing terminals. Each sensor nodes has the capabilities to acquire data from the ground and route data to the convergent node, now there are four types of data which are the temperature of soil, the moisture of soil, the temperature of air and the moisture of air. The convergent node is responsible for transmission data or instructions between sensor nodes and terminals. The paper also covers the design of power mangement and waterproof shell. The WSN presented in the paper attended the union experiment including satellite remote sensing, aerial remote sensing and ground verification which was organized by Chinese Academy of Sciences in Linze county, Gansu Province, China in July 2008.
