AIR MONITORING SYSTEM

Abstract

This paper talks about a system designed to monitor air quality using two sensors — MQ135 for detecting general air pollutants and MQ7 for measuring carbon monoxide (CO) levels. Keeping track of air quality is important because it helps people understand pollution and encourages healthier living, especially for future generations. The system supports environmental efforts like those of the Indian government, which has taken steps such as banning highly polluting motorcycles. This project uses IoT platforms like Thing Speak and Cayenne to show real-time pollution data on public dashboards. This lets anyone easily check the air quality in specific areas. Compared to older systems, this one offers better sensor calibration, gives more accurate pollution readings (in PPM), and is cheaper to build thanks to the use of affordable components. Overall, it’s a cost-effective and easy-to-use solution for monitoring the environment and spreading awareness about air pollution.
