Air pollution problem is becoming increasingly serious.Therefore

an accurate air monitoring system is of great social significance.However

the existing monitoring means has poor real-time

hard to maintain

and difficult to meet actual need.Aiming at these circumstances

an monitoring system based on Zig Bee technology is designed and the whole frame structure and implementation scheme is described.The system includes two parts:wireless sensor networks and remote monitoring center.The wireless sensor networks consists of sensor nodes and gateway nodes.The sensor nodes are built with CC2530 which are responsible for collecting air environment datas and sending data in real-time to the gateway nodes through multi-hop mode

and the gateway nodes are built with LPC2138 which is responsible for collecting datas of sensor nodes and communicates with remote monitoring center via GPRS.The remote monitoring center uses monitoring softwave programmed in Microsoft Visual C + + 6.0

accomplishes data receiving

displaying and storage

through network module

which provide a friendly interface of man-computer.
