Introduction

The DFRobot Heart Rate Monitor Sensor is used to measure the electrical activity of the heart.

This electrical activity can be charted as an ECG and output as an analog reading. An ECG

signal can be extremely noisy so we have included an AD8232 chip on the PCB which will

provide a clear signal from the PR and QT Intervals. Using the Arduino IDE "Serial Plotter"

feature you are also able to view plotted ECG output on your PC!

NOTE: An ECG signal can be quite noisy because of muscle activity. The further

sensor pads are from the heart, the more muscle noise you will see. To improve the

signal quality, follow these simple tips:

 Keepsensorpadsasclosetotheheartasyoucan

 MakesuretheRAandLAsensorpadsareoncorrectsidesoftheheart

 Trynottomovetoomuchwhiletakingameasurement

 Trytousefreshpadsforeachmeasurement.Thepadsloosetheabilitytopass

NOTE: If you found there was a lot of jamming waveforms, they may come from the

body's static electricity. Touch something metal to discharge any static electricity.
