Overview 📝
The AD8232 ECG Module is an integrated signal conditioning block for ECG and other biopotential measurement applications. It is designed to extract, amplify, and filter small bio-potential signals in the presence of noisy conditions, such as those created by motion or remote electrode placement. This kit is a favorite for engineering students working on Biomedical Engineering projects, wearable health tech, and fitness monitors.
Key Features ✨
Single-Lead Monitoring: Simplified setup compared to clinical 12-lead systems; uses just 3 electrodes (Right Arm, Left Arm, Right Leg).
Lead-Off Detection: Built-in “LO+” and “LO-” pins notify your microcontroller if an electrode falls off the user’s body.
Analog Output: Connects directly to the ADC (Analog-to-Digital Converter) pin of an Arduino, ESP32, or Raspberry Pi.
Integrated Filter: Features an on-board high-pass and low-pass filter to ensure a smooth, readable heart-wave on your Serial Plotter.
Compact Design: Small enough to be integrated into wearable prototypes or handheld health gadgets.
