INTRODUCTION
The DFRobot heart rate sensor is a thumb-sized heart rate monitor designed for Arduino microcontrollers.
This sensor is a pulse sensor which is developed based on PPG (PhotoPlethysmoGraphy) techniques. This is a simple and low-cost optical technique that can be used to detect blood volume changing in the microvascular bed of tissues. It is relatively easy to detect the pulsatile component of the cardiac cycle according to this theory.
