基于STM32的酒精检测仪设计 摘要：当前随着我国经济水平的迅猛提升，人们的收入和以往相比也得到了显著提高，此时买车的人越来越多，而因为酒后驾车，从而引发的交通事故也不断增多，在其他方面由于酗酒或特殊环境，也发生了许多令人感到悲伤遗憾的事故，酒精检测仪可以有效地减少这方面的事故发生。 在本文中主要介绍了基于STM32F103C8T6单片机设计的酒精检测仪，此次设计的这个检测仪主要由三部分构成，首先是OLED显示屏；其次是MQ-3乙醇气体传感器，最后是单片机，其型号为STM32F103C8T6。在预热之后，此检测仪能够利用自身的气体传感器来对空气里酒精浓度情况进行采集，将采集的信息依次由检测仪的A/D转换电路以及单片机处理之后，酒精浓度值就能够显示于显示屏中，此时检测仪的检测功能便得以实现。此设计可以在各种环境下进行酒精浓度的检测，可用于交通安全或酒厂、食品加工工厂等地点，有效提高安全性。 关键字：STM32F103C8T6单片机 MQ-3传感器 OLED显示屏 Design of Alcohol Detector Based on STM32 St Abstract: At present, with the rapid improvement of Chinas economic level, peoples income has also increased significantly compared to the past. At this time, more and more people buy cars, and the number of traffic accidents caused by drunk driving is also increasing. In other respects, due to alcoholism or special circumstances, many sad and regretful accidents have also occurred, and alcohol detectors can effectively reduce accidents in this area. ????In this article, the alcohol detector based on STM32F103C8T6 single-chip microcomputer is introduced. The detector designed this time is mainly composed of three parts, first is the OLED display; second is the MQ-3 ethanol gas sensor, and finally is the single-chip, its model STM32F103C8T6. After warming up, the detector can use its own gas sensor to collect the alcohol concentration in the air. After the collected information is processed by the A / D conversion circuit of the detector and the single-chip microcomputer, the alcohol concentration value can be displayed in In the display screen, the detection function of the detector can be realized at this time. This design can detect the alcohol concentration in various environments, and can be used in traffic safety or wineries, food processing factories and other places to effectively improve safety.
