Gravity: Analog Heart Rate Monitor Sensor (ECG) for Arduino Shipping:4-6 Days The charger testing range isThe 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 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! To ease the difficulty of using this
