本内容包括MAX30100的官方技术手册以及驱动代码
General Description
The MAX30100 is an integrated pulse oximetry and heart-rate monitor sensor solution. It combines two LEDs, a photodetector, optimized optics, and low-noise analog signal processing to detect pulse oximetry and heart-rate
signals.
The MAX30100 operates from 1.8V and 3.3V power sup-plies and can be powered down through software with negligible standby current, permitting the power supply to emain connected at all times.
