The invention relates to the technical field of automobile sensors, in particular to a double-channel gas sensor which comprises a shell, two air inlets and two air outlets are formed in the shell, a mounting plate is arranged in the shell, two detection channels, two air channels and two airflow guiding devices are arranged on the mounting plate, the detection channels are located on the front face of the mounting plate, and the two air channels are located on the rear face of the mounting plate. The air duct is arranged on the back of the mounting plate; one end, close to the air inlet, of each detection channel is provided with a temperature detection module, the other end of each detection channel is provided with a PM2.5 detection module, the middle section of any detection channel is provided with an AQS detection module, and the position, close to the air outlet, of any air channel is provided with a CO2 detection module. According to the vehicle-mounted fresh air system, the detection modules of various gases are integrated, detection of the various gases can be achieved, detected signals are transmitted to the air conditioner controller through CAN bus signals, and the air conditioner controller controls adjustment of the air conditioner mode or controls starting of the air purification system, so that circulation of the vehicle-mounted fresh air system is achieved, and freshness of air in the whole vehicle is kept.
