The invention discloses a vehicle-mounted ethyl alcohol monitoring system based on thermoelectric power generation and a conditioning amplifying circuit. The vehicle-mounted ethyl alcohol monitoring system comprises an ethyl alcohol sensor, the conditioning amplifying circuit, a filter circuit, an analog-digital conversion module, a microcontroller module, an ignition control device, a display module, a button setting module, a monitoring reset module, a sound-light alarm module, a JTAG interface module, a power supply module and a voltage change circuit. According to the vehicle-mounted ethyl alcohol monitoring system, as the ethanol sensor with the ultrahigh sensitivity, a single-chip microcomputer with ultra-low power consumption and an alcohol concentration automatic detecting method are adopted, a driver can be prevented from getting out of detection, and whether the driver is in drunken driving or not can be judged.
