An Overview Of Modern Iot Based Sensor Usage In Construction Of Better Air Quality In Rural-Urban Area Of Madurai And Tamilnadu

Abstract

A serious threat to the environment and human health is air pollution, especially in rapidly expanding cities and the rural areas that surround them. This research investigates the use of contemporary Internet of Things (IoT)-based sensor technologies to monitor and improve the quality of the air in Tamil Nadu's Madurai district, taking into account both urban and rural environments. The study evaluates important pollutants including PM2.5, PM10, NO₂, SO₂, and CO while integrating real-time data collection using Internet of Things-enabled air quality monitoring equipment. A comparison of rural and urban areas reveals the differences in air pollution levels and identifies major causes, including residential fuel usage, industrial activity, transportation emissions, and agricultural burning. The report suggests data-driven pollution control measures including smart ventilation systems, neighbourhood awareness campaigns, and policy-driven suggestions for environmentally friendly building and urban design. The results show how IoT can revolutionise environmental monitoring and how crucial it is to integrate smart sensor infrastructure to create healthier and cleaner living spaces in both urban and rural areas.
