Overview

Product Overview

The MAX30102 is an optical heart-rate and pulse-oximetry sensor: red (660 nm) and infrared (880 nm) LEDs with a photodetector and an 18-bit ADC sampling at 50–3200 samples per second. It talks I2C at address 0x57 (up to 400 kHz), and the module's onboard regulators accept 1.8–5 V, so it works with 3.3 V ESP32 and Raspberry Pi boards as well as 5 V Arduinos. Active current is under 600 µA, standby 0.7 µA.

Use the SparkFun MAX3010x or equivalent library to read pulse rate, estimate SpO2, detect a finger on the sensor and experiment with heart-rate variability. The 18 × 13 mm board comes with pins pre-soldered, as a single or a 2-pack. For wearables, fitness prototypes and biomedical learning — not a medical device.

Questions & answers

Frequently asked questions

Does the MAX30102 sensor work with Arduino and Raspberry Pi?

Yes. This MAX30102-based module is intended for Arduino, Raspberry Pi, ESP32, and similar microcontroller projects that can communicate over I2C. Use a suitable software library or driver for your chosen board and programming environment.

Is the MAX30102 module ready to plug in?

The module comes with pre-soldered pins, so it can be connected to a breadboard or jumper wires without soldering header pins first. You still need to wire it correctly and install compatible code or libraries.

What interface does the MAX30102 sensor use?

The MAX30102 communicates over I2C, so typical connections are power, ground, SDA, and SCL. Match the module’s power and logic requirements to your controller board, and avoid assuming it is compatible with every voltage level without checking your setup.

What projects can use this pulse oximeter module?

It is commonly used for wearable health monitors, fitness trackers, biomedical prototypes, data loggers, and IoT health demos. The module combines pulse-rate and SpO2 sensing on one compact board, reducing the need for separate heart-rate and oxygen-sensing modules.

Why are MAX30102 readings unstable or inconsistent?

Optical pulse and SpO2 readings can be affected by finger placement, motion, pressure, and ambient light. Keep the sensor steady against the skin, reduce movement, and treat results as project or prototype data rather than certified medical measurements.
