ABSTRACT

Air pollution has created a big impact on humans. This abrupt rising of pollutants in the air contaminates it and make it hazardous for living. Earlier the air we breathe in use to be pure and fresh but now a days, due to the abrupt rise in urbanization, industrialization, and associated anthropogenic activities are the main reasons that lead to air pollutant emissions and degradation of air quality. It is expected that by 2030, around 50% of the global population will be residing in urban areas. More than 80% of population in urban areas is exposed to emissions that exceed the standards set by World Health Organization (WHO 2016) .Also as per WHO (2016) estimates, 10 out of 20 most polluted cities in the world are in India. Hence it is necessary to take several steps by which we can check the quality of air at different locations. We tried to set up a small Intelligent air pollution monitoring system where we are using MQ315 sensor which senses the pollutants present in the air and will give the output in form of voltage pulses. Further those pulses will get converted into ppm scale and hence we can check the quality of air present in a particular region. This proposed work requires less instrumentation with less area of installation and hence it could be deployed at any location and will display the level of pollution of that particular region. So by this proposed work, one can get the real time values of the pollutants present in the air of a particular geographical area in form of a graph via ThingSpeak server and one could also get the SMS alerts on their devices if the pollution rises above a certain level. As we have used Arduino uno microcontroller in our proposed work, that's why we are naming it as an IoT based air pollution monitoring system.
