ECG Module AD8232 Heart ECG Monitoring Sensor Kit for Arduino

The AD8232 ECG Module Kit is a compact and cost-effective heart rate monitoring solution designed for biomedical and fitness applications. It detects electrical activity of the heart, outputs it as an analog signal, and can be used with Arduino and other microcontrollers to visualize ECG waveforms.

At its core, the AD8232 chip includes a precision operational amplifier, which helps extract clean PR and QT interval signals, reducing noise caused by motion or poor electrode placement. This makes the module highly reliable for detecting heart rate and monitoring cardiac activity.

The LED indicator on the board pulses in synchronization with the heartbeat, providing a real-time visual signal of heart rhythm. With its simple interface, the module allows easy integration into DIY health monitors, remote patient tracking, and fitness applications.

Key Features
