摘　　要：本设计采用ST测试系统,收集驾驶员呼出的气体,通过MQ-3酒精浓度传感器检测酒精浓度,再经过A/D转换器进入单片机控制器,将酒精浓度值通过LCD屏显示出来,当实时浓度超过规定阈值时,发出报警提示。The design uses ST test system to collect the exhaled gases of drivers, detects the alcohol concentration by MQ-3 alcohol concentration sensor, then enters the MCU controller through A/D converter, and displays the alcohol concentration value through LCD screen. When the real-time concentration exceeds the prescribed threshold, alarm prompts are issued.
