The MAX30100 operates on the principle of photoplethysmography (PPG). It emits red and infrared light into biological tissue (typically a fingertip or earlobe) and measures the light absorption by pulsating arterial blood with its integrated photodetector. The absorbed signal is processed by a high-performance, low-noise analog front-end before being digitized and made available via the I2C bus.
This sensor module provides a complete, calibrated solution that simplifies the design of heart rate and blood oxygen saturation monitoring systems. Its integrated design mitigates challenges related to optical alignment and signal conditioning. Developers should note that measurement accuracy can be affected by significant subject motion, extreme ambient temperature shifts, or excessive physical pressure on the sensing site.
