Low Cost Portable Emission Tester using Bluetooth and Android Application

Abstract: Emissions of many air pollutants have been shown to have a variety of negative effects on public health and the natural environment. With the ever increasing population and the need for automobiles for transportation, the number of vehicles have increased considerably which has lead to increase in the emission of air pollutants such a CO, CO2, Hydrocarbons, SO2, etc., which may cause grievous problems to living beings and environment. One solution to this problem is frequent monitoring of the gases in the environment. In India, the present emission monitoring system is available only at emission testing centers located either in petrol bunks or few other places. The model we have designed can be handed over to the traffic police for continuous and instant monitoring of emission levels of vehicles. The present standard device is not portable and involves wired connections unlike our design which is portable, rechargeable and wireless. These features make our design easier to use than the traditional device. Also, our new model is comparatively cheaper than the existing device with the same level of accuracy. Unlike the present emission testing device our model uses an android application to monitor emission levels and does not require any paper work. Moreover, we express our distress in the present emission monitoring system which involves multiple malpractices by manipulating the recorded emission levels for bribe. This can be eliminated by our device which includes instant and real-time monitoring of emission levels of vehicles already certified.

LITERATURE REVIEW

Environmental issues are caused by harmful human activities on the biophysical environment. This paper addresses one of the major environmental issues which is air pollution and steps to monitor and check the same. Environmental protection is a practice of protecting the natural environment at individual, organizational or government levels, for the benefit of the environment and all living beings. In this paper we develop a model which can monitor the emission levels of automobiles wirelessly and record the real time values. Monitoring of emission levels from time to time is vital to check and reduce air pollution caused by emission of fatal gases like CO2, CO, Methane, SO2, etc., by automobiles into the atmosphere which can cause devastating effects to the environment and living beings. Increase in carbon emissions causes green house effect and further leading to global warming. .Increase in the levels of air pollutants can lead to bronchitis, asthma, emphysema or COPD (Chronic Obstructive Pulmonary Disorder) and also lung cancer. Recently due to increase in air pollution in New Delhi, India has lead to the formation of thick smog leading to many fatal diseases. This forced the government in New Delhi to implement the „Odd/Even‟ scheme.
