Excellent sensor module
Very sensitive to finger placement. Once you get the position right, the pulse detection is quick. Great for learning about biometric sensors.

Great for Arduino projects
Works perfectly with the standard libraries. I used it for a fitness tracker prototype and the data logging is stable. Just remember this is for development, not medical diagnosis.

Fast delivery and well packed
Arrived sooner than expected. The module looks sturdy and the PCB quality is good. I am using it with an ESP32 for a IoT health project.

Learning curve exists
Had some trouble with I2C pull-up resistors initially. Support helped me figure out the wiring. Works now but requires some electronics knowledge.

Good value sensor
Pin headers were not included so I had to solder them myself. Once set up, the I2C communication was straightforward. Readings seem consistent for a hobby module.
Q: Is this sensor medical grade certified?
A: No, this module is intended for hobbyist and development purposes only. It is not certified for medical diagnosis or treatment.
Q: Can I connect this directly to a 5V Arduino Uno?
A: Yes, the module includes a voltage regulator and logic level shifting, making it safe to use with 5V microcontrollers like the Arduino Uno.
Q: Are there libraries available for this chip?
A: Yes, there are several open-source libraries available for Arduino and PlatformIO that support the MAX30102 protocol.
Q: Does it work through clothing?
A: No, the optical sensors require direct skin contact to measure heart rate and blood oxygen levels accurately.
Q: What are the required wiring connections?
A: You need to connect VCC, GND, SDA, and SCL pins. Ensure you have appropriate pull-up resistors on the SDA and SCL lines if your board lacks them.
