It is necessary to have a methane concentration detector in the coal mine workspace. In this paper, a methane detector is designed which is based on non-dispersive infrared spectrum absorption theory and employs the single-light beam and double wavelength differential detection technology and integrative infrared filter detector. Performance test for this system has been conducted, and the experimental data has been fitted and relation formula between methane concentration and voltage under different temperature has been given .The results of experiment indicates that the detector can effectively detected methane concentration and had lower measurement error and higher detection sensitivity and can be primarily used in coal mine.
