ABSTRACTABSTRACTPulse meter in our daily life have got the very extensive application.In order to improvethe simplicity and accuracy of the apparatus used to measure the pulse,this topic has designed apulse measuring instrument based on 52 microcontroller.System with STC89C52 single-chipmicrocomputer as the core,with original ST188 infrared reflection type sensor for the detection,and use the single chip microcomputer system internal timer to measure time,pulse generated bythe reflecting type of infrared sensor ST188 induction,microcontroller pulse is obtained by thepulse accumulation number,time by the timer timing.System can display the pulse frequencyand time,the system stops running,can display the total pulse frequency and time.After the test,the system works well,to meet the design requirements.Keywords:The pulse measuring instrument;STC89C52 single-chip microcomputer;The infraredreflection type sensorIV
