The AD8232 SparkFun 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 analog 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. It is designed to extract, amplify, and filter
small biopotential signals in the presence of noisy conditions, such as
those created by motion or remote electrode placement.
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, GND provide essential pins for operating this monitor with
an Arduino or other development board. Also provided on this board are
RA (Right Arm), LA (Left Arm), and RL (Right Leg) pins to attach and use
your own custom sensors. Additionally, there is an LED indicator light
that will pulsate to the rhythm of a heart beat. Biomedical Sensor Pads
and Sensor Cable are required to use the heart monitor and can be found
in the Recommended Products section below.
