|
Optical, using light absorption modulation via capillary filling pulsations.
|
Light wavelength
|
940nm (infrared)
|
Light noise
immunity
|
Light noise is minimized using ELP(Environment Light Protection) technology.
|
Heart Beat
Detection method.
|
High Precision Peak Detection from 2nd Derivatives of PPG.
