Gravity: Arduino Heart Rate Monitor Sensor (ECG)
37 units available with a short lead time.
The DFRobot Gravity Heart Rate Monitor Sensor measures the electrical activity of the heart and outputs it as an analog signal. Built around the AD8232 chip, it filters and amplifies the ECG signal to produce a clean waveform from the PR and QT intervals — viewable in real time using the Arduino IDE's Serial Plotter.
The Gravity interface allows plug-and-play connection with compatible Arduino boards and shields. Operating at 3.3–5V, it's also compatible with Raspberry Pi and other 3.3V microcontrollers.
