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 breakout operates from 1.8V and 5.5V power supplies and can be powered down through software with negligible standby current, permitting the power supply to remain connected at all times..
