MAX30100 on ESP32


#1

Hello everyone,
I’m a student of the University of Salerno (UNISA) and I’m developping a simple driver to interface the ESP32 board to a MAX30100 (Datasheet).
The main problem is that I don’t know how to read Oxygen percentage and heart reat even if I set the correct mode. Now I’m able to read only temperature in burst read;
I attach the links to my code to this post.

Hi @VITO_CARROZZA,

your code seems ok, unfortunately that sensor does not provide direct values for heart rate and oxygen percentage which have to be somehow computed. Here you can find a library with some useful calculations.
