Abstract

Objective: Developing an efficient computer aided odour detection system for odour classifying and categorizing samples in more efficiency. Methods/Analysis: Among few approaches, the author have proposed the approach for the identification of chemical vapor is to build a cluster of sensors where each cluster will sense a specific chemical. During the experimental analysis, a sensor array consisting of two sensors have been used with an Arduino board and a PC or Laptop. Verification program has been developed in order to verify the system functions. Authors have used MS Visual C++ for developing the computational interface. Findings: Results generated from experiments gives an indication that the developed system was capable of identifying the odors’ of LPG and Alcohol. The developed system shows the intensity of both LPG and Alcohol odour present at certain time. A siren also blows if intensity of any odors’ goes beyond any threshold value. Application/Improvement: If the proposed system uses large number of various type of sensors instead of only two sensors it will shows the intensity of different odors’ present at that time and different sensor’s result do not interfere with each other, that is they are very selective in nature.
