Low-cost PM Sensors Performance, Drift Analysis, Calibration and Optimal Deployment

This research work, introduces the method to find agreement among low-cost sensors in collocation (Intervariability) monitoring PM Concentrations and ways to correct it. Variability observed in extreme ranges of humidity, temperature and level of concentration. Further, unreasonable layout of sensor nodes is optimized in the monitoring network and showed that monitoring of air pollution of an entire area can be possible using only a few significant nodes. In future, this reliable PM sensor based AQM system can be used on Terrestrial and Aerial Mobile Platforms for PM monitoring. PM concentration values generally higher at places, which are heavily trafficked and close proximity to construction activities. Real-time pollution tracking is another possibility using this reliable and stable mobile AQM system prototype integrated with UAVs.
