Design and implementation of a cost effective gas pollution detection system

With the current increase of air pollution rates and its threats to human life, starting from global warming to health problems, the need for more efficient and cost effective pollution measurement system arises. In developing countries the cost of the equipment is one of the obstacles that contribute to not having an efficient monitoring system. In this work I am presenting the design of computer based pollution detection and measuring system using commonly available sensors (O₂ sensors available in cars). The proposed work concentrate on measuring percentage of CO (carbon monoxide) in combustion engine emission and in the atmosphere and the use of the device to judge whether an area pollution or an engine emission is above or below the average level. The device is cost-effective and could be used with and without computer and addresses the demand of developing countries. A C# based program is also designed to show and log the sensor readings in an easy to use and read Window.
