The DFRobot Gravity Heart Rate Monitor Sensor measures the electrical activity of the heart, allowing you to record and visualize ECG (electrocardiogram) signals. Built with the AD8232 chip, it delivers a clean, amplified signal from PR and QT intervals, reducing noise for more accurate readings.

Using the Arduino IDE's Serial Plotter, you can view real-time ECG waveforms directly on your PC — perfect for biomedical projects, health monitoring systems, or educational demonstrations.

If you need additional ECG electrodes, they are available separately.
