One fiber laser CH4 detection system based on the spectrum absorption is provided. The system has the advantages such as high accuracy, fast response and highly specific and so on. But the absorption coefficient of the methane and the characteristic of the electronic and optic device are all affected by the temperature. So the test value has interdependency to the environment temperature. In this paper, we give the measure principle of the detector and the analyses of the data which last one month uninterrupted. And then the temperature compensate was introduced to improve the performance of the detector.
