Product Description
The AD8232 ECG Heart Rate Monitoring Sensor Module is a compact analog front-end designed to extract, amplify, and filter biopotential signals from the human heart. It is often used as a basic single-lead electrocardiogram (ECG/EKG) sensor in wearable health devices, biofeedback systems, heart rate monitors, and medical experimentation projects.
The module includes onboard amplification, filtering, and a reference output that makes it easy to interface with microcontrollers like Arduino, ESP32, STM32, Raspberry Pi (using ADC), and others that can process analog input. With its low power consumption and simple pinout, the AD8232 is ideal for projects involving heart monitoring, pulse rate detection, and other physiological signal acquisition.
