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!

Connection Diagram

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
signals with multiple applications
• Prepare and clean the area you plan to stick pads. This will help make a good
connection hair is not a good conductor
• You may have to adjust sensor placement for different individuals

Expected Result

Open the Arduino IDE or above "Serial Plotter";

Open "Serial Plotter"

Then you could see the output signal from the microcontroller A1 port, the ECG.

Sample output of this sensor

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. More read on WikiHow.
