Environment monitoring system is an application service system for the management of industry and agriculture and the construction and operation of the national economy, which is conducive to the protection of the environment and ecology, can effectively avoid major environmental pollution incidents to threaten people's lives and property safety, and provide information support to safe energy system and to more efficient cooperative-work. The wireless sensor network is the product of the combination of sensor technology, communication technology and computer network technology. The wireless communication technologies in wireless sensor networks include infrared, Bluetooth, Wi-Fi, and ZigBee, etc.. ZigBee technology is a set of communications technology for networking, security and application software with developed based on the IEEE 802.15.4 wireless standard, which are provided with low-power, low-latency, high security and other technical advantages. In this paper, the ZigBee wireless sensor network was used for data acquisition, wireless transmission in environmental monitoring site, which overcame the disadvantages and difficulties from traditional manual sampling monitors and from complicated wiring cable network monitoring. Quickly through ZigBee network data transmission to the monitoring platform to provide a reliable basis for environmental monitoring.
