The MAX30102 module is a versatile sensor module that integrates a pulse oximeter and heart-rate monitor, designed to measure both the heart rate and blood oxygen saturation (SpO2) levels of a person. This module utilizes optical sensors and advanced algorithms to noninvasively monitor physiological parameters by shining light through a person's skin and measuring the light absorption variations caused by blood flow and oxygenation changes. The MAX30102 module finds applications in fitness tracking devices, wearable health monitors, medical instruments, and sports equipment.
