IoT Based Air Quality Monitoring System Using Arduino

In this work, Internet of Things (IoT) system has been devised to monitor in real time the basic pollutants like Carbon dioxide, Carbon monoxide, Particulate matter, Temperature, Humidity, Pressure. The Primary focus of this paper is to monitor air quality at indoor and outdoor level of residential and industrial sectors by using in total of five sensors, ESP8266 Wi-Fi module and Arduino Uno. The emission from vehicle modeling and vehicle’s other emissions can be monitored easily through the internet. A real time air quality monitoring system is essential for Bangladesh especially in Dhaka City because, here the pure air is getting denser and polluted day by day. All sensors real-time data will be displayed on LCD and only the humidity and temperature will be shown on the server. With the help of this project, we have been able to take real-time data of the North and the South side of Dhaka city in February 2023 and plotted curves in Excel. After the analysis of output curves from the Excel plots, we found out our air is very polluted and getting thicker day by day.
