A gas pattern recognition method using gas sensor array detection combined with nearest neighbor algorithm is proposed.An experimental system is designed for gas identification based on this method.It proves that this method has the advantages of few experiments with high identification accuracy.In the experiment
the gas sensor array is composed of three metal-oxide semiconductor gas sensing sensors
and the experimental process and the identification results are discussed in detail.Experimental results show that the success rate of correct identification for the three gases methane(CH4)
