Methane and Carbon Monoxide Gas Detection system based on semiconductor sensor

One of the most important actual problems in the gas detection field is that there are strong demands for gas methane leak detection and CO (carbon monoxide) detection to prevent explosions or CO poisoning accidents. In this sense, the present paper describes technical characteristics, test results, and a concluding application for methane and carbon monoxide based gas detection using a sensor which can detect both CO and methane with a single sensing element. The paper presents the detection method as well as the apparatus functional sketch
