Pollution is escalated by developments that typically occurs when countries develop through rising towns, upward traffic, high-speed economic activity, industrialization, and excessive levels of energy employment. The supplementary opening of the metropolitan areas to people, land use patterns and trade development have led to the complicated threat of air pollution. Air pollution is a key factors for the constituents in the environment and leads to global warming and acid rains. To arrest such dangerous imbalances in nature, air pollution monitoring system is of utmost significance. Wireless Sensor Networks (WSNs) constitute tremendous technology solutions that can identify, determine, and assemble data from the real world and convey the sensed data to the user, based on a quantity of local estimation process. These networks are conform with the physical environment, which is premeditated and at elevated resolutions adding value and sum of real-world data and information for applications analogous to pollution monitoring. One of the purposes behind the sensors is that if commercialized, they would caution people to be more rational every day while dealing with air pollution. Users can keep away from areas where the levels have been cruelly elevated, and can be imagined to put pressure on local powers to address the issue. Also, data gathered using multiple sensors across a region could provide the public with much supplementary information for being careful and present precise air worth reports than is currently possible.
