IoT-based air pollution detection, monitoring and controlling system

Abstract

Air pollution is one of the most concerning and alarming problems in the modern world, and it is increasing day by day due to a large number of industries and urbanization. When pollutants are released into the air from several sources, such as the combustion of fossil fuels, industrial emissions, agricultural sources, and so on, it is referred to as air pollution. It is acknowledged as a significant risk factor for noncommunicable diseases (NCDs) that include lung cancer, stroke, heart disease, and acute and chronic respiratory illnesses including asthma. An estimated seven million individuals die globally every year due to air pollution as the world health organization reported on their website. In this paper, we have proposed an Internet of Things (IoT) based air pollution detection, monitoring, and controlling system. The system detects the various air pollutants by combining the different sensors, helps users to monitor the received pollutants levels over LCD, user’s mobile app, and cloud server, and controls the air quality up to a certain level when pollutants levels cross the threshold limits. NodeMCU plays an important role to exchange the data or information between the proposed system devices. We have designed a prototype for demonstrating the proposed system performance. The prototype testing and result show’s that the proposed system works significantly well in terms of detection, monitoring, and controlling air pollution, especially proposed controllers exhibit impressive performance for maintaining the air quality.
