AN EFFECTIVE AND PORTABLE IOT BASED AIR POLLUTION MONITORING SYSTEM

Abstract: Air pollution has the potential to harm both current and future generations. Despite numerous government initiatives to restrict this, pollution levels have increased significantly in comparison to the regulations in place. As a regulatory safeguard, a gadget can be used to monitor air pollution in one’s home or office, and preventive measures can be taken to reduce pollution on a basic level. For this, we used sensors and a broadcast that sends every update to a mobile device on a time-to-time basis, allowing us to monitor and implement effective pollution-prevention actions. In this paper, we utilized MQ4, MQ9, and DHT22 sensors in conjunction with a Microcontroller Arduino Uno ATmega328p and a GSM (Global System for Mobile Communication) module, which allows a mobile device or computer to talk to a wireless network. The time and level of contaminants in the air are displayed on an LCD (Liquid Crystal Display) screen, allowing for monitoring and required preventive steps to be implemented. This proposal contains cost-control measures so that one of these devices can be installed in every home, gated community, or factory to monitor and regulate pollution levels. The levels are presented in real time on both the LCD and the mobile app for easy and effective monitoring
