Solid component for the price
For the cost, you cannot beat this module. It's not a clinical-grade device, but for testing algorithms and building fitness tracker concepts, it is ideal.

Excellent data output
The FIFO buffer helps prevent data loss during high-speed sampling. The raw data output is clean and easy to process on an ESP32. Very satisfied with this purchase.

Sensitive to ambient light
Works well indoors, but struggles with accuracy if there is strong sunlight interference. You need to build a good enclosure to block external light for best results.

Good sensor, needs calibration
The hardware quality is solid. However, getting accurate SpO2 readings required some careful calibration against a medical device. Not for medical use, but great for learning.
Q: What is the maximum sampling rate supported?
A: The MAX30100 chip supports programmable sample rates up to 1000Hz, though typical heart rate applications usually operate between 50Hz and 100Hz.
Q: Is a 5V logic level safe for the I2C pins?
A: While the board can be powered by 5V, the I2C logic lines are 3.3V. If your microcontroller uses 5V logic, we recommend using a logic level converter to ensure safety.
Q: How do I reduce noise in the readings?
A: Ensure the sensor has firm contact with the skin, block ambient light with an opaque cover, and utilize the built-in digital filtering options in the library settings.
Q: Does this module come with example code for Arduino?
A: Yes, there are several open-source libraries available on GitHub that include example sketches for reading heart rate and SpO2 data using Arduino IDE.
Q: Can this be used as a certified medical device?
A: No, this module is intended for educational, prototyping, and hobbyist purposes only. It is not calibrated or certified for medical diagnosis or treatment.
