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.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Electrode Placement: For the best signal at your Pimpri facility, follow the standard triangle placement: Right Arm (RA), Left Arm (LA), and Right Leg (RL) for the reference electrode. Using medical-grade conductive gel can further improve signal clarity.

  • Power Stability: The AD8232 is sensitive to power supply noise. We suggest adding a 10uF capacitor across the 3.3V and GND pins of the module to filter out ripple from your microcontroller's regulator.

  • Safety First: This module is for educational and prototyping purposes only. It should never be used for medical diagnosis or life-critical applications. Never connect the electrodes to a subject while the microcontroller is powered by a wall-socket AC adapter; use a battery to ensure complete electrical isolation.

  • Serial Plotter: To see your heartbeat in real-time, use the "Serial Plotter" tool in the Arduino IDE. Simply analogRead() the signal pin and Serial.println() the value to visualize the ECG wave.

Package Includes
