Good sensor, needs calibration
The hardware quality is solid. However, getting accurate SpO2 readings requires careful calibration and proper finger placement. Once set up, it tracks heart rate very well.

Perfect for STM32 projects
This module works flawlessly with my STM32 development board. The I2C communication is stable, and the library support is excellent. Great value for prototyping wearable sensors.

Compact and reliable
Impressed by how small yet functional this breakout board is. The soldering points are clear, and it integrates easily into custom PCB designs. Highly recommended for students.

Solid performance for the price
We use these in our workshop for various IoT demos. They are durable and provide good signal quality. Just ensure you have a stable 3.3V power supply for best results.

Great for learning biometrics
Bought this for a university project on health monitoring. The data output is consistent, and the interrupt features help save power. Excellent educational tool.

Works but documentation could be better
The sensor itself functions as expected, but finding clear example code specifically for the MAX30102 on STM32 took some digging. Once I found the right registers, it worked fine.
Q: Can this measure blood pressure?
A: No, the MAX30102 sensor is designed specifically for measuring heart rate and blood oxygen saturation (SpO2). It cannot measure blood pressure directly.
Q: Are the header pins pre-soldered?
A: Yes, all our MAX30102 modules ship with the 8-pin header strip pre-soldered, so they are ready to plug directly into a breadboard immediately upon arrival.
Q: Is this module compatible with 5V logic levels?
A: Yes, the breakout board includes voltage regulation and level shifting, making it safe to use with both 3.3V and 5V microcontrollers like the STM32 or Arduino Uno.
Q: What is the maximum sampling rate?
A: The MAX30102 supports sampling rates up to 3200 Hz, though typical heart rate and SpO2 applications usually operate between 50 Hz and 100 Hz to balance accuracy and power consumption.
Q: Does this come with example code for STM32 HAL?
A: The package does not include physical media, but we provide a link in the product description to a GitHub repository containing STM32 HAL library examples and driver code.
