The Proposal of Gas Discrimination by Using Fuzzy Reasoning

Abstract

We tried gas discrimination by using one semiconductive gas sensor.
As a method of gas discrimination, we used the fuzzy reasoning with fuzzy set of slope of gas pattern which is divided into arbitatry interval.
As a result, we got a good successful rate for hydrogen 66.6%, propane 79.1%, butane 100%, methan 100%, city gas 79.1%, and alcohol 91.6%.
