Overview

Product Overview

Heart rate and pulse oximeter sensor module based on the MAX30102, this compact I2C biometric sensor measures pulse rate and SpO2 blood oxygen levels for wearable health monitors, fitness trackers, and biomedical prototyping. The combined sensing design helps you add vital-sign monitoring to Arduino, Raspberry Pi, ESP32, and other microcontroller projects without needing separate boards for heart rate and oxygen sensing. Its I2C interface keeps integration straightforward for embedded systems, data logging, and real-time health measurement demos, while the small module format fits portable electronics and custom enclosures. With pre-soldered pins for easier hookup, it is a practical choice for rapid development of wellness devices, research builds, and IoT health projects.

Questions & answers

Frequently asked questions

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.
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.
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.
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.
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.
