Shi Y., Wu Q., Lu X., 2018, Design and Implementation of WSN Detection System for Harmful Gas Based on Odour Recognition, Chemical Engineering Transactions, 68, 355-360.
In view of the safety problem with the harmful gas leakage in chemical environment, this paper develops one wireless sensor network (WSN) detection system for harmful gas based on odour recognition. In this system, the sensor array is used to make odour recognition of the four harmful gases such as Cl2, CO, NO2 and SO2 in the chemical environment; then, the data is transmitted through the ZigBee technology-built WSN to the central sink node for data analysis. Thus, the effective recognition and detection of harmful gases in the chemical environment can be achieved so as to avoid potential safety hazards.
