AIR POLLUTION MONITORING : A NEW USE OF MOX SENSORS, CELLULAR PHONE NETWORK AND MICROCONTROLLER

摘要

Air pollution is a serious problem in urban areas of India and other developing countries. The number of automobiles has increased to N-fold due to rise in population and improved standard of living. The exhaust from the automobiles is one of the main causes for air pollution in the urban areas. Hence, it is the important area to be monitored continuously to improve the air quality in metro and urban areas. Ban of usage of automobiles with more than 15 years age, insisting Bharat Ⅲ Standards for new vehicles and making periodical pollution check ups mandatory are few steps taken by the government. Government also has employed a team has to verify all pollution level verification certificates regularly. Physical verification of all such certificates is not only tedious, but also incomplete. As the automobile has to be taken to pollution check centre for pollutant level verification regularly, there is a possibility of human negligence. In the present study, an attempt is made to use MOX sensors, cellular phone network, and micro-controllers to develop a new system, such that exhaust gas monitoring for automobiles can become automatic and simple.
