AD8232 Heart Rate Monitor Kit

The AD8232 Single Lead Heart Rate Monitor is a cost-effective board used to measure the electrical activity of the heart. This electrical activity can be charted as an ECG or Electrocardiogram and output as an analogue reading. ECGs can be extremely noisy, the AD8232 Single Lead Heart Rate Monitor acts as an op-amp to help obtain a clear signal from the PR and QT Intervals easily. The AD8232 is an integrated signal conditioning block for ECG and other biopotential measurement applications. Designed to extract, amplify, and filter small biopotential signals in the presence of noisy conditions. For example, those created by motion or remote electrode placement.

The AD8232 Heart Rate Monitor breaks out nine connections from the IC that you can solder pins, wires, or other connectors to. SDN, LO+, LO-, OUTPUT, 3.3V, and GND provide essential pins for operating this monitor with an Arduino or other development board. Provided on this board are RA (Right Arm), LA (Left Arm), and RL (Right Leg) pins to attach and use your own custom sensors, in addition, there is an LED indicator light that will pulsate to the rhythm of a heartbeat. Included are the Biomedical Sensor Pads and Sensor Cable required to use the heart monitor.
