Because methane is an inflammable and explosive gas, it is indispensable to monitor methane. It is very useful to develop a portable methane detector in order for the application multiple purpose, such as coal mine safety monitoring. This paper gives a prototype design of a portable methane gas sensor with 1.65μm LED. Sensor is made by a 1.65μm LED and high responsivity photo receiver. The experimental result shows nearly linear at low methane concentration. And a prototype portable gas sensor has been demonstrated.
