AD8232 Heart Rate Monitor Kit with ECG Sensor Module – Single-Lead Heart Rate Monitor Front End for Arduino, Robotics

Product Description

Unlock the power of biomedical engineering with the AD8232 Heart Rate Monitor Kit. This specialized module is a cost-effective integrated front-end designed to extract, amplify, and filter small bio-potential signals in the presence of noisy conditions. At Robogears, we recommend the AD8232 for its exceptional ability to produce a clear Electrocardiogram (ECG) wave from just three leads. The module acts as an op-amp specifically tuned for heart rate monitoring, featuring a specialized filter that eliminates the motion artifacts often caused by breathing or limb movement. Whether you are building a fitness tracker or a medical diagnostic prototype at your Pimpri workshop, this kit provides a professional-grade starting point for heart rate data acquisition.

Detailed Key Features

• Single-Lead Front End: Specifically designed to extract and amplify biopotential signals from the heart while rejecting electrode half-cell potential.

  
  

• Integrated High-Pass & Low-Pass Filtering: Features a two-pole high-pass filter that eliminates motion artifacts and a three-pole low-pass filter to remove line noise.

• Fast Restore Function: Includes a "Fast Restore" feature that quickly recovers the signal after lead-off conditions or abrupt signal changes.

  
  

• 3.5mm Bio-medical Connector: Equipped with a standard 3.5mm jack for easy connection to the included electrode cables, ensuring a secure and low-noise interface.

  
  

• Leads-Off Detection: Built-in circuitry detects if an electrode has become disconnected, providing a dedicated digital output for system monitoring.

All Technical Details

• Analog Output: The signal can be directly connected to the Analog-to-Digital Converter (ADC) of an Arduino or ESP32 for easy digital processing.

• Power Efficiency: Designed for low-power operation at 3.3V, making it suitable for battery-operated wearable prototypes.

• Common-Mode Rejection: Features high CMRR (Common-Mode Rejection Ratio) to ensure the heartbeat signal is clean even in electrically noisy environments.

• Applications: Portable ECG monitors, fitness heart rate trackers, game control via biometrics, and educational health-tech projects.
