PAH8001EI-QG
PAH8001EI-QG
Optical Heart Rate Detection Sensor
General Description
The PAH8001EI-QG is a high performance and low power CMOS-process optical sensor with Green LED and DSP
integrated serving as a Heart Rate Detection (HRD) sensor. It is based on optical technology which measures the
variation of human blood movement in the vessel.
Key Features
