Low Power MAX30102 Sensor Heart Rate Breakout Board For Arduino Blood Oxygen Sensor Module MAX30100 Pulse Oximeter

MAX30102 Sensor Module – Heart Rate & Blood Oxygen Sensor for Arduino

The MAX30102 Sensor Module is a compact, low-power optical sensor designed for heart rate and blood oxygen (SpO2) monitoring. It integrates red and infrared LEDs with a photodetector to measure pulse and oxygen levels through the fingertip. With its I2C interface and small size, it is perfect for Arduino, mbed, and other microcontroller platforms.

This module is an upgrade to the MAX30100, offering better signal accuracy, ambient light cancellation, and lower power consumption, making it ideal for wearable devices, DIY health monitors, and portable fitness trackers.
