"基于单片机的汽车酒精浓度检测装置设计及应用研究"

With the increasing number of households owning cars, a new problem has emerged - drunk driving. Drunk driving has led to a rising number of traffic accidents, causing huge losses to both life and property. Nowadays, people have become more aware of the dangers of drunk driving, leading to greater attention being paid to alcohol testing devices. In order to reduce and prevent drunk driving accidents, a device has been specially designed to detect alcohol concentration in the air, using gas sensors and a single chip computer as its main components, with the added feature of an LCD display. This design collects gas-related data through gas sensors, which is then modulated and converted by the alcohol concentration sensor module. The data is then transmitted to the single chip computer for processing and execution of relevant functions. The LCD screen displays the alcohol concentration in the gas, and users can set a threshold value through buttons. If the threshold is exceeded, the system will emit a warning light and other functions will be activated. Keywords: Single chip computer; Alcohol concentration detection system; Gas sensor. Overall, the design of the alcohol concentration detector based on a single chip computer provides a reliable solution to the issue of drunk driving. By utilizing advanced technology and innovative components, this device offers a practical and effective way to detect alcohol levels in the air and prevent potential accidents. The integration of gas sensors, alcohol concentration sensor modules, and a single chip computer ensures accurate measurements and efficient data processing, ultimately contributing to the safety of drivers and pedestrians on the road.
