Overview
The alcohol detection module is designed to detect alcohol content in a driver’s exhaled breath. By accurately measuring alcohol concentration, it effectively prevents drunk driving, ensuring road safety and protecting lives and property. The module uses an electrochemical fuel cell-type alcohol sensor, integrated with a temperature sensor for temperature compensation, ensuring measurement accuracy and reliability. In addition, the module is integrated with a pressure sensor to detect the blowing action, further guaranteeing the authenticity of the measurement. The measurement data can be transmitted through a serial port signal, which is convenient for integration with the vehicle’s electronic control system.
