The Design of Methane-monitoring System Based on ZigBee Network

To meet the requirements of monitoring environments and detecting the methane concentration in the in- dustrial-mining field, the paper analyzes the faults of the current monitoring technology,and puts forward a new method of detecting the methane concentration based on the ZigBee wireless sensor technology. We adopt the infrared spectrum absorption principle to measure accurate concentration of the methane, use ZigBee wireless receiving and transmitting modules to control the collecting, dealing and the transmitting of the methane concentration, realizing the wireless con- centration measurement of the self-networking. The system structure, the hardware scheme and the design of the software are given in this paper.
