Instructions:PulseSensor is a photoelectric reflective analog sensor for pulse heart rate measurement.
Wear it on the finger, earlobe, etc., through the wire connection, the collected analog signal can be transmitted to the arduin0 and other single-chip microcomputers for conversion to digital signals, and then the heart rate value can be obtained by simple calculation by the arduin0 MCU, and the pulse can be obtained.
The waveform is uploaded to the computer to display the waveform.
