Abstract
In the last half century, the world population migrated from villages to cities due to lack of facilities, education institutes, medical services, and job opportunities in the remote areas. Due to this migration the big cities are under pressure to remain live-able and healthier because population increasing quickly as compared to the services infrastructure. As the city's population increasing very rapidly and demand for the civic facilities remains very high. One of the major additions is the road traffic which become the big contributor in air pollution and make the environment very unhealthy. In modern era, it is important to persistently monitor the environmental pollution of city to make it healthier and live-able. Internet of Things (IoT) with smart sensor system is the solution which can be used to monitor the city for various purposes and one of them is the pollution monitoring in big cities. Sensor system can be installed and managed by integrating with IoT and be monitored by sitting in city central office. In this research work, a framework for air quality monitoring is proposed to monitor environmental pollution for the smart cities by using IoT and smart sensors. The proposed system is capable to measure the humidity, carbon emission, temperature, smoke, sound and other hazardous particulate in the atmosphere and send the measurements to city central office where it is analyzed for further actions for the betterment of city environment. Collected data is banked in a data bank for future use and can be shared with other research institute and environmental agencies.
