From wireless sensor works and GPRS work of carbon monoxide monitoring system can bring about longdistance realtime data collection from a large number of sensor nodes deployed in the region to monitor for the acquisition of carbon mono xide information,via GPRS works to deliver the information tothe farmonitoring centre which conn ected the Inter the staff through the analysis of the data which were received and published timely it information, provide the basis for urban planning. Passed the test of the system, the system is work ing well. The main contents and conclusions are as is a kind of standard that emerges in recent years as short distance wireless munieation technical,and hasits own unique superiority when it is applied In the wireless sensor the Gas Density Monitoring system based onZigBee emerged as the times require. The paper designed and implemented the system based on ZigBee against a backdrop of sme main work is as follows: the zigBee protocol standards and framework of the over all structure of the Gas Density Monitoring system and work topology depe nd on specific environmental of smelter. the main chiP and development Platform,Pleted the hard ware design of the terminal n ode, realized the AD converter module,a wireless sendingModule,power supply module. the reduced ZigBee stack,plete the design of software of the terminal nodes and coor dinator. the software of PC一 monitoring,which had some functions such as serial port settings, threshold value settings,data base proeessing,dynamic chart s and so on,based on MFC in d evelopment environment. the concentration of gas monitoring system and gave the results. The system had met the basic design goal and reflected ZigBee technology own Unique superiority when it was applied in monitoring area through the design and test of the concentration gas of monitoring system base ZigBee. In addition to this， the circuit for the node was designed:including wireless module and expanding module. The experiment was carded out and the experimental results were also results show that the designing has reached the expected work could form the topology configuration successfully and the data Can be transmitted in the light of the routing mechanism designed.
