Analysis of a Data Acquisition System for a Compact Electronic Nose

Electronic nose systems have been recently in use for various applications ranging from environmental monitoring to biomedical applications. This paper introduces a compact electronic nose system integrating conducting polymer sensors with data acquisition, data processing and storage unit. The data acquisition system presented here is equipped with a graphical user interface (GUI) to control the acquisition parameters as well as perform analysis on obtained data. The real-time data acquisition system is capable of collecting data from an 8X8 resistive sensor array as per the parameters passed by the GUI. Finally, the paper is concluded with results and discussion obtained using the proposed electronic system. The result shows with proper classification algorithm, the system is capable of identifying various amine and alcohol groups.
