Title: Development of an IoT based Air Quality Monitoring System
Abstract: The proposed work aims for a large-scale air pollutant monitoring for ambient and indoor environments. This system is developed to measure various environmental parameters. Sourceof pollutants can be identified by analyzing the data collected from the various sensor nodes, so that air quality can be monitored by applying engineering science and data. This is achieved by installing multiple sensor stations in various locations such as hospitals, factories, Offices, streets and weather stations. These sensor stations measure the environmental parameters such as PM2.5, PM10, Sulphate (SOx), Nitrate (NOx), Ozone(O3), Volatile Organic Compounds (VOC), Temperature and Humidity. The sensor stations communicate with cloud over HTTP protocol. Each station has ESP 8266 smart controller which captures the sensor data and creates forms theJavaScript Object Notation (JSON) data packets that mainly consists of sensor data along with node address. These packets will be sent to the cloud over HTTP protocol. The user can access the air quality data from the web application.
