AD8232 ECG Sensor Module

The AD8232 ECG Sensor Module is a compact, reliable solution for measuring the electrical activity of the heart (ECG) and monitoring heart rate in real time. Based on the Analog Devices AD8232 integrated signal conditioning chip, this module is ideal for low-power, wearable health applications and educational biomedical projects.

Designed to extract, amplify, and filter small biopotential signals, the AD8232 provides clean analog output suitable for ECG waveform analysis and heart rate detection.

Key Features:

• Single-Lead ECG Measurement: Captures heart electrical signals for waveform and heart rate analysis.

• Low Noise Analog Output: Ideal for real-time data capture and visualization using Arduino, ESP32, or Raspberry Pi.

• Integrated Signal Conditioning: Built-in amplifier and filter for clean signal extraction.

• 3.5mm Jack & Pin Headers: Supports standard ECG electrodes or custom connections.

• LED Indicator: Blinks in sync with detected heartbeats.

Specifications:

• Operating Voltage: 3.3V to 5.0V DC

• Typical Current Consumption: ~170 µA (ultra-low power)

• Output Signal: Analog ECG waveform (0–3.3V typical)

• Interface: 3-pin header (Analog Out, GND, 3.3V/5V Power), plus LO+ and LO- (Lead-Off detection)

• Board Dimensions: Approx. 35mm x 25mm

• Operating Temperature: -40°C to +85°C

Applications:

• Wearable heart rate monitors

• DIY fitness and health tracking projects

• Biomedical signal experiments

• Educational ECG demonstration systems

This module is perfect for makers, developers, and students interested in exploring biopotential sensing and real-time heart monitoring.
