Best pulse sensor

Update 2: I tried using the Sparkfun MAX30105 library with my MAX30102 breakout board and my Argon. This was the first library that led to mild success.

I wired it as followed (using Sparkfun’s MAX30105 guide)

Argon       MAX30102 breakout
  D0             SDA (no pullup)
  D1             SCL (no pullup)
 3V3             Vin
 GND             GND

I had problems running the sample code, but the specific heart rate example seems to work

The value seem to jump around a lot and not completely stay persistent. For anyone that has used these breakouts, is that normal?

From my experience, this Sparkfun MAX30105 library was the only one I could get to successfully work with Argon.
