Ozone and Nitrogen Dioxide Pollutants Detection System Based on IoT

Abstract

        Air pollution is one of the main causes of health problem in urban areas. Vehicles are the major sources of the air pollution in urban cities. To prevent the air pollution situation from increasing, we have developed an advanced outdoor air quality measurement system using a ESP8266 microcontroller and senores. It can be placed at crowded automobile locations to monitor pollutants emitted from vehicles. Ozone gas (O₃) and nitrogen dioxide (NO₂) was measured in this study. The system provides continuous monitoring of vehicle air pollution with a high time accuracy.
