AFE4900: PPG measurement voltage.

Daeho Kim

Part Number: AFE4900

Hello.

I have a question about the PPG sensor of AFE4900.

The value will be different depending on the measurement location, but it is very different as follows. Would this be correct?

The measured value is -10mV to 15mV when measured on a finger, -0.4mV to 0.4mV when measured on a wrist. Is this correct?

Can you confirm?

I'd appreciate it if you could check.

Thank you.

Regards.

Hello Daeho,

Your observation is correct. Depending on the measurement site, other physiological parameters such skin tone and the mechanical design of the product, the strength and quality of the PPG signal will vary.
