The AD8232 ECG sensor is a commercial board used to calculate the electrical movement of the human heart. This action can be chart like an Electrocardiogram and the output of this is an analog reading. Electrocardiograms can be very noisy, so to reduce the noise the AD8232 chip can be used. The working principle of the ECG sensor is like an operational amplifier to help in getting a clear signal from the intervals simply.

The AD8232 sensor is used for signal conditioning in ECG as well as other measurement applications of bio-potential. The main purpose of this chip is to amplify, extract as well as filter bio-potential signals which are small in the noisy conditions like those formed through the replacement of remote electrode as well as motion
