Abstract

In the proposed paper, a wireless sensor platform was developed to addresses the problem of air pollution monitoring at a large scale. It is a Microcontroller PIC 16F877 based core with off the shelf sensors to detect gases like Sulphur Dioxide (SO2), Carbon Monoxide (CO), Ammonia (NH3), and Particulate matter (PM10) in the air. It consists of Global System for Mobile Communications (GSM) wireless link and also a low-cost ZigBee module. Wireless sensor network formed with ZigBee links can be scaled up using the GSM connectivity to interface with the external world. Air Pollution monitoring is performed using a system of sensor nodes with the help of wireless communication via ZigBee protocol. A prototype version of the platform is realized and tested. The major problem of power consumption by the sensor nodes in the designed wireless sensor network is addressed. The results showed that the proposed system can provide fine quality of air pollutants information through the WSN technology.
