MAX30102 Pulse Oximeter Heart Rate Sensor Module I2C Interface

The MAX30102 Pulse Oximeter Heart Rate Sensor Module is a compact optical sensor board designed to measure blood oxygen saturation (SpO2), heart rate, and pulse via reflecting IR and red light from body tissue. It integrates the MAX30102 sensor IC with onboard I2C interface and signal processing support for easy digital communication with microcontrollers.

This module is ideal for wearable health devices, fitness monitors, biomedical projects, and embedded health measurement systems. The low power design, built-in LED drivers, and I2C communication enable accurate and efficient physiological data acquisition in portable applications.
