I created a finger holder to help take heart rate measurements using the Max30102 sensor. This holder makes it easier to consistently position the finger and avoid mistakes. I hope this is helpful for others who are using this sensor.

The accuracy of PPG measurements can be affected by factors such as heart rate and the sensitivity of the measurement system. However, the position of the finger on the PPG sensor can also impact the reliability of the readings. I would prefer to use a fingerclip, but for convenience, I will use this finger holder.
