Works but documentation could be better
The sensor functions as described, but I had to dig through forums to find the right register settings for low-power mode. Good for experienced users.

Good sensor, needs calibration
The hardware quality is solid. However, getting accurate SpO2 readings requires careful calibration and consistent finger placement. Once tuned, it works well.

Great for the price point
Compared to other sensors in this category, the MAX30102 from Youxin offers great performance. Just ensure you have a stable 3.3V power supply.

Reliable data output
Using this for a long-term heart rate logging project. The FIFO buffer helps prevent data loss during high-frequency sampling. Highly recommended.
Q: What is the maximum sampling rate?
A: The MAX30102 supports sampling rates up to approximately 3200 Hz depending on the configuration of the sample average and resolution settings.
Q: Is this suitable for medical diagnosis?
A: No, this module is intended for hobbyist, educational, and fitness tracking purposes only. It is not certified for medical diagnosis or clinical use.
Q: Can this measure blood oxygen without a finger clip?
A: The module provides raw optical data. To measure SpO2 accurately, you typically need a mechanical fixture or clip to ensure consistent contact and block ambient light.
Q: Does this module come with a library for Arduino?
A: Yes, it is compatible with popular open-source libraries like SparkFun MAX30102 and Adafruit_MAX30102 available in the Arduino Library Manager.
Q: Does it work with 5V logic microcontrollers?
A: The sensor operates at 1.8V-3.3V. If using a 5V microcontroller like an Arduino Uno, you must use a logic level converter or an I2C breakout board with level shifting.
