Wireless sensor network node includes: the perception component, embedded processor, memory, and communication software components this several parts. Wireless sensor network is composed of one or more base stations (Sink node) and a large number of deployed in the monitoring area. This paper proposes design and implementation of monitoring information system based on wireless sensor network technology. The monitoring system is composed of sensor network terminal node, a number of small amounts of the sink node, a gateway node and the background monitoring system.
