Other Parts Discussed in Thread: TIDA-01580
Hello.
I testing a PPG sensor of AFE4900.
I am using a PPG sensor to measure SpO2 on wrist.
However, there is a difference in data between IR and Red, so the SpO2 value cannot be accurately found.
* PPG Sensor(SFH7072) Red, IR LED current : 20mA same
I think I measured it with finger on TIDA-01580.
How do I measure SpO2 on wrist?
I would appreciate it if you could check and answer.
thank you.
Regards.
