This sensor module employs a reflective photoplethysmography (PPG) principle. The MAX30101 utilizes integrated LEDs and photodetectors to measure light absorption variations in blood vessels, providing raw optical data. The onboard MAX32664 Biometric Sensor Hub, a Cortex-M4 based processor, handles all complex signal processing, including digital filtering, R-wave detection, and pressure compensation, outputting fully processed heart rate and SpO2 values via I2C.
The module is designed for reliable performance in dynamic environments, featuring integrated cover glass for optical stability and robust mechanical protection. Its Qwiic connector simplifies wiring, requiring only connection to power, ground, and I2C lines for rapid integration into wearable fitness monitors, hearables, portable medical devices, and mobile health applications.
