1. Introduction to PulseSensor
(1) Working principle
PulseSensor is a photoelectric reflective analog sensor for pulse and heart rate measurement. Wear it on the finger or earlobe, etc. through wire connection, the collected analog signal can be transmitted to stm32, Arduino and other MCU, and analog-to-digital conversion (voltage acquisition ...
