Theprincipleofdripspeedmeasurement:theinfraredemissiontubeiscontrolledby
theMCU,andtheinfrarediscontinuouslytransmittedtosendinfrared.Normally,the
infraredreceptiontubecanreceivethesignaloftheinfraredemissiontube.Whenthe
medicinedrops,the waterdropswill block the infrared reception. At this time, it is
judgedthatthereisadrop,andtheMCUwillcalculatethedropspeedaccordingto
theblockingtimebetweenthetwodrops.
