Abstract—An online GPRS-Sensors Array for air pollution
monitoring has been designed, implemented, and tested. The
proposed system consists of a Mobile Data-Acquisition Unit
(Mobile-DAQ) and a fixed Internet-Enabled Pollution Monitoring
Server (Pollution-Server). The Mobile-DAQ unit integrates a
single-chip microcontroller, air pollution sensors array, a General
Packet Radio Service Modem (GPRS-Modem), and a Global Positioning
System Module (GPS-Module). The Pollution-Server is a
high-end personal computer application server with Internet connectivity.
The Mobile-DAQ unit gathers air pollutants levels (CO,
NO2, and SO2), and packs them in a frame with the GPS physical
location, time, and date. The frame is subsequently uploaded to
the GPRS-Modem and transmitted to the Pollution-Server via the
public mobile network. A database server is attached to the Pollution-
Server for storing the pollutants level for further usage by
various clients such as environment protection agencies, vehicles
registration authorities, and tourist and insurance companies. The
Pollution-Server is interfaced to Google Maps to display real-time
pollutants levels and locations in large metropolitan areas. The
system was successfully tested in the city of Sharjah, UAE. The
system reports real-time pollutants level and their location on a
24-h/7-day basis.
