Description The MAX30102 Sensor Module Breakout is a highly integrated optical sensor solution designed for heart rate monitoring and pulse oximetry (SpO2) measurement. Featuring ultra-low power consumption and a compact 12.7mm × 12.7mm board size, this module is ideal for wearable devices, medical monitoring projects, and Arduino-based health systems. This sensor combines LEDs, photodetectors, optimized optics, and low-noise analog signal processing to deliver reliable non-invasive heart-rate and oxygen saturation measurements. Unlike chest-strap monitors, the MAX30102 allows for comfortable finger-based or wearable detection, making it suitable for smart health devices and fitness trackers. The MAX30102 Sensor Module Breakout includes device drivers, free algorithm support, and example C source code for both Arduino and mbed platforms. With its I2C communication interface, integration into microcontroller projects such as Arduino, ESP32, STM32, or Raspberry Pi is straightforward. Designed for ultra-low power applications, the MAX30102 is perfect for battery-operated devices, wearables, and portable medical monitoring systems.
