ArduEmission: vehicular emissions monitoring

Air pollution is on the rise due to a number of anthropogenic activities and its monitoring is of vital importance. In cities, vehicular emissions are chiefly responsible for the rise of various air pollutant gases in the atmosphere. Due to high density of vehicles in mega cities, there is a constant need for air pollution monitoring and quality assessment of these vehicles in terms of their emission standards. This paper describes a portable, easy-to-use and cheap electronic sensor based system for monitoring the vehicular emissions. This electronic sensor based system is called ‘ArduEmission’ as this device uses Arduino microcontroller for its functioning. This device is easy to use and the data obtained from it can be easily stored, analyzed and plotted in real-time using the software developed for ArduEmission. In this paper, the technique for using and calibrating the device has been elucidated and various vehicles are then examined using this device for their emissions of Carbon Monoxide gas in the atmosphere.
