Add Reliable Heart Rate Monitor Sensor Gravity Sensing to Your Next Build
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.

Pinout & usage notes
Check the supported input voltage before wiring so the module matches your controller and power source. Verify serial levels, baud rate, and pin mapping in the official DFRobot guide before first power-up. If you are using Gravity connectors, align the plug correctly and avoid forcing the cable into the wrong header.

Frequently Asked Questions
Can I use this for logging or monitoring projects? Yes. It is a good fit for data collection, automation, and alert-based builds when paired with a supported controller.
Does it work with other boards too? Often yes, as long as voltage, interface, and pin mapping match. ESP32 and Raspberry Pi users should still check the official docs first.
Where can I find wiring and examples? Use the official DFRobot product page and wiki links below for guides, downloads, and code examples.
