Real-Time Emission Monitoring and Display to Reduce Vehicle Pollution Using Wireless Network

There are several sensors operating in a car to control different aspects of the car performance. Among those, “NOx exhaust gas sensors” are responsible for catalyst performance, which helps the emission reduction of the vehicles. The focus of this paper is to design cost effective industrial wireless networks for the use of data transfer from NOx sensors to an on-board visual display. The instantaneous and cumulative pollution produced by a car are valuable data for environment and studying the correlation between fuel consumption and driving behavior. In this paper we study how above data can be accessed, transmitted and provided to the driver. Various design strategies are presented. The implementation of the developed hardware and software are shown to produce good verification results.
