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.

    本发明及汽车传感器技术领域,尤其是一种双通道气体传感器,包括壳体,壳体上具有两个进风口和两个出风口,壳体内设有一安装板,安装板上设置有两个检测通道、两个风道以及两个气流引导装置,检测通道位于安装板的正面,风道设置在安装板的背面;检测通道靠近进风口的一端设有温度检测模块,检测通道的另一端设置有PM2.5检测模块,任一检测通道的中段设有AQS检测模块,任一风道靠近出口风的位置设置有CO2检测模块。集成了多种气体的检测模块,能够实现多种气体的检测,将检测到的信号通过CAN总线信号传给空调控制器,由空调控制器控制空调模式的调整,或者控制空气净化系统的开启,从而实现车内新风系统的循环,保持整个车内空气的清新。
