Introduction

The DFRobot heart rate sensor is a thumb-sized heart rate monitor designed for Arduino

microcontrollers. It includes a Gravity interface, for easy plug-and-play connectivity.

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.

The sensor has two holes that you can use to attach to your belt. You can wrap on your finger,
