Good value, requires calibration
The hardware is solid and supports HRV analysis as advertised. It took some time to calibrate the filters for my specific use case, but once set up, the data stream is stable.

Reliable heart rate detection
Works flawlessly with my ESP32 project. The heart rate variability metrics seem accurate when compared to reference equipment. Highly recommended for hobbyists and pros alike.

Great module, minor noise issues
Overall a fantastic sensor. I experienced some electrical noise initially, but adding a simple shield resolved it. The support team was helpful in troubleshooting.

Perfect for prototyping wearables
This module made it incredibly easy to integrate ECG monitoring into my prototype. The documentation for secondary development is clear, and the signal quality is impressive for the price point.
Q: Is this compatible with Arduino Uno?
A: Yes, the module is fully compatible with Arduino Uno. You will need to connect via UART or SPI, and sample code is available in our documentation repository.
Q: Can I use this for continuous 24-hour monitoring?
A: While the sensor is capable of long-term operation, continuous 24-hour monitoring depends on your power management setup and battery capacity, as the module itself does not include an internal battery.
Q: What type of electrodes are included in the kit?
A: The kit includes standard snap-type disposable ECG electrodes and a connecting cable. Replacement electrodes can be purchased separately from most medical supply stores.
Q: Does this module provide raw ECG data or just the calculated heart rate?
A: The BMD101 provides both real-time calculated heart rate and raw ECG waveform data, allowing for custom signal processing and secondary development.
Q: Is there a library available for Python integration?
A: We currently provide C/C++ libraries for embedded systems. For Python, you can read the serial output using standard PySerial libraries, and several community-contributed wrappers are available on GitHub.
