Abstract
For the scene where there is a toxic gas leak, in order to detect the gas quickly and safely and make the effective solutions, the project of monitoring toxic gases in a remote wireless way and the process of the development is proposed in this paper. The device developed in this paper includes several wireless sensor network (WSN) nodes and one hand-held terminal, and the sensor module of WSN node is composed of several chemical gas sensors. The nodes will be sent to the scene by ground robots or unmanned aerial vehicles and make up the WSN monitoring system automatically, to achieve an aim of monitoring the toxic gas in real time. The experiment results show that the device can deal with the emergencies about the leak of toxic gas efficiently. And it has the advantages of low power consumption, high cost performance, self-forming network, anti-interference. Its suitable to monitor the toxic gas in various environments of industrial production and chemical scene of accident and unexpected occasions where there is a leak of toxic gas.
