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,
wrist, earlobe or other areas where it has contact with skin. The heart sensor has two kinds of signal output mode analog pulse mode and digital square wave mode. You can change its output mode using the dial switch. There are many user scenarios, including education, sport or maker/interactive projects!

Board Overview

NOTE The switch is to set the working mode, it will change the signal type to be Digital or Analog. If it was NOT set as consistent as the code or wiring, i.e. the switch was set as "A", but you write your code as digitalRead and or you wire the module onto Arduino digital pin, in this case, you will fail to get any readings, vice versa.

Tutorial

Through this tutorial, you will learn how to use this Heart Rate sensor in digital mode as well as analog mode, more than this, at the end of this tutorial, we will show you how to use this sensor to draw the ECG to a LCD module. Requirements
• Hardware o 1 x DFRduino UNO or similar o 1 x This Heart Rate Sensor o 1 x IO Expansion Shield for Arduino suggested o Some wires
• Software o Arduino IDE Click to Download Arduino IDE from
• Library o Sample Code on Github, How to install Libraries in Arduino IDE?

Before start Once you opened the box, you could find the black belt inside of the package. Thread it through the holes of the sensor as indicted out in the photo. And then you could attach it on your finger suggested , wrist or any other places where exposes blood vessels. Do not attach the belt too tight or too loose to your finger, or the reading might be not stable. Besides that, during the test, you should steady your finger, do not move too much, or the readings would be bad.
