Abstract

Multimedia systems are widely used in consumer electronics environments today, where humans can work and communicate through multi-sensory interfaces. Unfortunately smell detection and generation systems are not part of today's multimedia systems. In this paper, we propose an Electronic Nose based on TGS-822 sensors that can be used in a multimedia environment. TGS-822 sensor based electronic nose can detect a large number of Volatile Organic Compounds (VOCs) that have some smell and will have a significantly lower cost compared to the other detection systems. The results and the calibration graph obtained for three VOCs (i.e. ethanol, acetone and benzene) with varying concentration shows that TGS 822 sensor has the potential to become a reliable instrument and can be used in an electronic nose. Therefore, the accuracy and linearity of the obtained characteristics with higher sensitivity of the proposed electronic nose based on TGS-822 sensor for the detection and determination of volatile organic compounds defines its effectiveness in a multimedia environment.
