The invention provides a gas detection device, and the device comprises a detection module which is used for detecting gas concentration information, and generating a first simulation detection signal according to the detected concentration information; the analog-digital conversion module is used for converting the first analog detection signal into a first digital detection signal; the processing module is used for judging whether gas leakage occurs or not according to the first digital detection signal; the gas detection device comprises power supply voltage, the power supply voltage supplies power to the detection module, the analog-digital conversion module and the processing module, and the power supply module is used for converting external alternating-current voltage into the power supply voltage and further used for converting external direct-current voltage into the power supply voltage. The gas detection device can be suitable for scenes of direct current power supply and alternating current power
