摘要
本文设计了一个基于单片机的酒精检测系统,通过MQ-3酒精传感器对气体中的酒精浓度进行检测,将采集的数据经A/D转换传到STC89C52单片机处理,然后在OLED屏上显示酒精质量浓度。当酒精质量浓度超过报警阈值时,系统发出声光报警并提示酒驾或醉驾。本系统具有体积小、价格低、实用性强、便携等特点,可广泛用于酒驾、醉驾的监测以及酒厂等场所酒精质量浓度检测。
In this paper,an alcohol detection system based on MCU is designed.The alcohol concentration in the gas is detected by MQ-3 alcohol sensor,and the collected data is transferred to STC89C52 MCU for processing by analog-to-digital conversion,and then the alcohol concentration is displayed on the LCD screen.If the alcohol concentration exceeds the alarm threshold,the system will give an audible and visual alarm and prompt drunk driving.This system has small volume,low price,strong practicability,portable,etc,can be widely used for the monitoring of drunk driving,and alcohol concentration detection in places such as distilleries.
