Max30100 Hear rate sensor

MAX30100 is an integrated pulse oximetry and heart-rate monitor sensor solution. It integrates two LEDs (IR and Red), a photodetector (Red), optimized optics, and low-noise analog signal processing to detect pulse oximetry and heart-rate signals. It is fully configurable through software registers, and the digital output data is stored is stored in a 16-deep FIFO within the device.

It has an I2C digital interface to communicate with a host microcontroller. The pulse oximetry subsystem in MAX30100 consists of ambient light cancellation (ALC), 16-bit sigma delta ADC, and proprietary discrete time filter. It has an ultra-low-power operation which makes it ideal for battery operated systems.

MAX30100 operates on a supply in the range of 1.8 to 3.3V.

It can be used in wearable devices, fitness assistant devices, medical monitoring devices, etc.
