Real Time Air Quality Monitoring

In this paper, a real-time crowd sensing based air quality monitoring system is presented. The proposed system uses low cost and low power devices with gas sensors to capture the air quality index from the atmosphere. Raw sensor data collected from the gas sensors sent to the cloud using an android application. In cloud, the data is stored and processed. The processed data is visualized in real time on a map using an open-source geospatial data visualization framework such as Leaflet using R programming.
