Air Pollution Monitoring System based on Wireless Networks - Simulation

Abstract

Air pollution is one of environmental issues that cannot be ignored. Industrial growth and urbanization results in the air pollutants concentrations in many areas. These pollutants can cause damages in human health and other living organisms. The available pollutant emission monitoring systems, such as Opsis, Codel, Urac and TAS-Air metrics are typically expensive. In addition, these systems have limitations to be installed on chimney due to their principle of operation. This causes other areas surrounding the factories being unmonitored and hence cause healthy issues. This paper proposes an industrial air pollution monitoring system based on the technology of wireless sensor networks (WSNs). This system is integrated with the global system for mobile communications (GSM) and its communication protocol used is zigbee. The system consists of sensor nodes, a control center and data base through which sensing data can be stored for history and future plans. The proposed system can be deployed to the industries for monitoring carbon monoxide (CO), sulfur dioxide (SO₂) and dust concentration caused by industrial emissions due to process.
