Actions #9

Updated by Hajira N 12 months ago

14/08/2025
----------
Partially done the project of measuring SPO2 and BPM using MAX30102. It gives some value, but sometimes it is showing some values out of normal range, and it is different from the values in the pulse oximeter. So I have to try more library functions with less usage of memory space and to avoid the current issue.
