Abstract
In this paper, the domestic gas discrimination system is proposed for practical use. The system is constructed by using a digital signal processor, and is able to use as an real-time, stand-alone system. The commercial base semiconductor gas sensor TGS823 is used and 3 gases i.e. inflammable gas, alcohol and cigarette smoke, are chosen as the subjects of the discrimination.
The results of discrimination experiments are shown to demonstrate the effectiveness of the proposed system.
