Abstract: The present invention relates to a method for detecting a gas concentration using a gas detection device, comprising: determining a first relationship between a baseline drift of the gas detection device with respect to a gas concentration and an environmental temperature and performing, based on the baseline drift of the gas detection device with respect to a gas having a first temperature, a first compensation on a gas concentration output value of the gas having the first temperature determined by the gas detection device. With such a method, a gas concentration check result is more accurate, and the gas detection device can be applied to a wider range of application scenarios.
