Heart Rate Sensor ECG compatible with Arduino®

The Heart Rate Sensor ECG 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 which will generate 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 PC!

Below shoes the diagram on how to connect the Heart Rate Sensor to an Arduino
