Alcohol concentration monitoring system based onsingle chip microcomputerAbstract:In recent years,accidents happen frequently,and most of them are caused bydrunk drivers.Therefore,an important measure to reduce traffic accidents is to testwhether people drink and drive.The design of alcohol concentration measurementsystem based on detection,content display and alarm based on single-chipmicrocomputer.Its function is to detect the alcohol content in the breath of thedriver through the MQ-3 alcohol concentration detection sensor,extract andconvert the data measured by the alcohol detection sensor by using the programrunning logic in the core controller of the instrument,and then display the readingon the display screen of the instrument.When the alcohol content in the breath ofthe detected driver exceeds the standard,the instrument will send a report Police,in order to remind police,the driver drunk driving.The invention,popularization andgeneral application of alcohol concentration measuring instrument based on singlechip microcomputer not only greatly reduce the probability of drunk driving,reducethe probability of traffic accident to the minimum,but also increase people's legalawareness,strengthen people's awareness of the law and awe of the law.Thisdesign is based on the design of alcohol concentration detection system ofsingle-chip microcomputer.Its core control chip is STC12C5A6052 single-chipmicrocomputer,which is a powerful single-chip microcomputer.The function of thissingle-chip microcomputer in this design is to extract,display and compare digitalsignals,so as to realize the extraction of detection data of MQ-3 gas alcoholconcentration detection sensor and the display through LCD screen And the audibleand visual alarm when the range is exceeded.Keywords STC12C5A60S2 single chip;LCD;acousto-optic alarm;MQ-3 alcoholconcentration detection sensor-2
