Datasheet
MAX30101 on Analog.com
I have connected a MAX30101 sensor to an STM32 microcontroller.
The settings are as follows:
I have controlled the LED current from 0 to 50 mA by increasing the current by 1mA each time. The MAX30101 is powered with a 3.3V logic level, and all LEDs are turned on simultaneously. However, I am unable to get a proper signal from the wrist area, but I can get a good signal from the fingertip.
Is there any specific position that needs to be considered, or can anyone guide me on this issue?
