Abstract
This paper presents a design of an alcohol concentration tester based on the STC89C52 microcontroller. The design utilizes the MQ-3 sensor to detect alcohol concentration, and when the concentration exceeds the predetermined maximum value, it triggers a sound and light alarm while simultaneously activating a water pump. Users can set the upper limit of alcohol concentration through buttons. Additionally, the design includes an LCD1602 display screen to provide real-time display of alcohol concentration data. This alcohol concentration tester is capable of fast and accurate detection of alcohol concentration in the environment, offering warning and control functions to ensure safety and mitigate potential alcohol-related risks. Through the research and design presented in this paper, the alcohol concentration tester serves as an effective tool for monitoring and controlling alcohol concentration in various industries and settings, providing security measures and reducing the occurrence of alcohol-related accidents. It holds significant practical significance and application value.
