【 摘 要 】

In this paper, we present our proposed air quality monitoring system with multiple data sources for smart cities. We deploy oursysteminoneofthebiggestcitiesinVietnam,HoChiMinhCity.Theproposedsystemusesdatacollectedbyoursensors and extracted from remote sensing images. The system also allows users to contribute by provide alerts through a portal. With data collected from sensors, we can provide exact values of fundamental parameters for calculating air quality index (AQI) while data extracted from remote sensing images help governors estimate the AQI values in surrounding areas withoutsensorsdeployed.Thisestimationalthoughcannotprovideexactinformationassensors,ithelpsustoquicklyunderstandAQIinanextremelylargeareawithlowcost.Alongwiththesedatasources,notificationsfromusersalsoallowgovernorstoreactunawarenessproblemsfaster.Experimentalresultsshowtheerror(difference)betweenoursystemsandcommercialdevicesislessthan24%forsensoringsystemandlessthan9%forremotesensingimagesestimation. The sensoring system presented in this paper is low-energy consumption when using only 900mW in average.
