Real-time Air Quality Index Monitoring and Alert System using IoT Technology

Abstract

Air pollution is one of the biggest problems of our time because it not only contributes to climate change but also has a negative influence on public and individual health, which raises morbidity and mortality rates. The general comfort and health of a building's occupants are significantly influenced by the indoor air quality (IAQ). Numerous detrimental health outcomes, such as allergies, headaches, and respiratory issues, can be brought on by poor IAQ. An IoT-based indoor air quality monitoring system can be used to solve this problem. We suggest a three-phase air pollution monitoring system to address the issues with current systems. With the help of gas sensors and a Raspberry Pi 4, an IoT kit was created. This device can actually be put into different rooms to monitor air pollution. The gas sensors collect information from the atmosphere and transmit it to the Raspberry Pi 4. The Wi-Fi module on the raspberry pi4 sends the data to the cloud. Users can get pertinent cloud-based air quality data via an android app that has been built. In order to efficiently monitor air quality and foresee the negative effects that prolonged exposure to these pollutants may have, our project aims to develop a real-time air monitoring system.
