Abstract

The frequent usage of sensory modalities for Advanced Driver Assistance System (ADAS) and in some In-Vehicles Information System (IVIS) are only for visuals and hearing applications. Yet, the air quality inside the car is not usually monitored. Not to mention, the existing breath analyzers are used only by road traffic police enforcer randomly in examining the alcohol content in motorist's breath to avoid drunk driving related accidents. In this study, we proposed the development and utilization of an e-nose sensory module as an added feature for Controller Area Network (CAN) technology application. An electronic nose is characterized by its capability to intelligently sensed the gases present in the surrounding using an array of gas sensors with a pattern reorganization component. This e-nose comprises of a sensor array of five commercially available sensors (TG 2602, TG 822, TG 825, TG 813 and TG 880), a data acquisition interface, and a microprocessor. A software from the CAN module verified the system functionality. Experimental results indicate that the proposed system is able to identify the five different types of gases namely methane, ethanol, propone, isobutane, and hydrogen with high efficiency. Thus, it can be used as an added safety feature for vehicles.
