Fuzzy Logic Application for Odor Detection

Abstract — Fuzzy logic is one of the techniques in Artificial Intelligent (AI) that widely used to control environmental factors. The effectiveness of fuzzy logic has been proven through a lot of creation of Intelligent System using fuzzy logic application. This paper presents the research segment of development of methodology for determining odor level using fuzzy logic based algorithm. Two different gas sensors are used which respond to carbon monoxide, methane, hydrogen, ethanol and chlorofluorocarbon. This study focused on evaluating the possibility of using gas sensor to detect odor level produced by coffee. Sensor fusion is achieved through processing the analog to digital converted values of sensor outputs using algorithm to determine the odor level of predetermined odors. Fuzzy logic algorithm is based on Zadeh-Mamdani type Fuzzy inference system approach. The result of this study will be displayed in form of percentage values and will be compared with the simulation result using Matlab
