MAX30102 Heart Rate & SpO2 Sensor Module

MAX30102 Pulse Oximetry & Heart-Rate Monitor Sensor

The Maxim MAX30102 is an integrated pulse oximetry and heart-rate monitor biosensor module. It combines two internal LEDs (660nm Red and 880nm IR), photodetectors, optical elements, and low-noise analog signal processing with ambient light rejection.

Specifications

• Dual Wavelengths: 660 nm (Red) and 880 nm (Infrared) LEDs
• Resolution: High-resolution 18-bit ADC with 32-sample FIFO buffer
• Communication: Standard I2C bus with programmable sample rates (50 to 3200 Hz)
• Operating Voltage: 1.8V logic / 3.3V LED drive (breakout module includes regulators)
• Ultra-low power: Under 600 μA in heart-rate mode, 0.7 μA in standby
• Applications: Wearable fitness trackers, fingertip SpO2 meters, bio-feedback
