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 sensing. When the obtained by fails to meet requirements, it automatically switches acquiring rhythm using scheme increasing pulse driving frequency.
