摘要

The heart rate sensing module LED estimates relatively accurate heartbeat data for hundreds of flashes per second. In most cases, PPG technology uses infrared for sensing. When the data obtained by infrared sensing fails to meet the requirements, it automatically switches to acquiring heart rhythm data using the PPG scheme by increasing the pulse driving frequency.
