Key Features of MAX30102 Pulse Oximeter Heart Rate Sensor Module
- Dual-Wavelength Sensing: Integrated red (660nm) and infrared (880nm) LEDs enable accurate pulse oximetry and heart rate detection using photoplethysmography (PPG).
- Ultra-Low Power Consumption: Draws only ~600uA during active measurement and drops to 0.7uA in shutdown mode - ideal for battery-powered wearables and portable health monitors.
- High-Resolution 18-Bit ADC: Built-in analog-to-digital converter captures fine signal variations for precise BPM and SpO2 calculations.
- Programmable Sample Rate & LED Current: Configure sample rates from 50Hz to 3200Hz and LED drive current from 0-50mA to optimize performance for your specific application.
- Internal 32-Sample FIFO: Onboard data buffer reduces microcontroller interrupt overhead and allows efficient batch data reads over I2C.
- Standard I2C Interface: Simple two-wire communication (SDA, SCL) at up to 400kHz - requires only 4 connections (VCC, GND, SDA, SCL) for basic operation.
- Ambient Light Cancellation: Built-in ambient light rejection and signal processing reduce noise from external light sources for reliable indoor and outdoor readings.
- Compact Breakout Board Design: Tiny module with onboard voltage regulator, level shifting, and standard 2.54mm header pins - plug directly into a breadboard or solder into custom PCBs.
- Interrupt Output Pin: Configurable INT pin alerts the microcontroller when new data is ready, FIFO is nearly full, or temperature reading is complete.
- Built-In Die Temperature Sensor: Internal temperature sensor (+/-1 degreesC accuracy) enables calibration compensation for improved SpO2 accuracy.
- Reliable Module Design: Quality breakout board with onboard 1.8V regulator, bypass capacitors, and proper decoupling for stable, noise-free operation out of the box.
- Extensive Library Support: Works seamlessly with popular Arduino libraries (SparkFun MAX3010x, DFRobot Heart Rate) - get readings in minutes with example code.
