Monitoring real-time urban carbon monoxide (CO) emissions using wireless sensor networks

Abstract

In this paper, we propose a wireless sensor network based portable pollution monitoring system for monitoring the carbon monoxide (CO) concentration levels on the real time basis. Carbon Monoxide which is a critical and primary pollutant in air significantly affects the health of the people. With the rapid industrialisation and the exponential growth of automotive vehicles had led to the deterioration of air quality in the urban areas. Our design consists of Testbed of five nodes with calibrated carbon monoxide sensors for measuring CO concentration levels. By using the multi-hop mesh network, the CO sensors are integrated onto the Waspmote to communicate between the various nodes for the information exchange. The derived concentration levels of carbon monoxide from the different sensors on the board are made available on the internet through the platform which consists of Light Weight Middleware and Net Interface deployed on the server. Designed prototype had been implemented and tested in collecting the emission levels of CO in the Hyderabad city which had shown the consistent results under various circumstances.
