Design and implement of a flammable gas detection system based on wireless sensor network

This paper introduces a flammable gas detection system based on wireless sensor network which adopts chip design of JN5139 and ZigBee. In this system, gas monitoring nodes can self-organize into wireless sensor network, monitor the gas leak status timely and upload to the monitoring center. Flammable gas concentration of each node can be displayed in real time. Once gas concentration is higher than threshold value, the audible and visual alarm will be started. And the information will be shown on upper computer, in order to inform the staff to handle it. The experimental results show that the system has quick, reliable and accurate functions.
