The MAX30102 Heart Rate & Pulse Oximeter Sensor Module is a compact optical sensor board used to read pulse signals and blood-oxygen (SpO2) data in DIY electronics and learning projects. Built around the popular MAX30102 chip, it pairs red and infrared LEDs with a photodetector so you can experiment with biosignal sensing on your own microcontroller. It suits students, hobbyists, makers and prototype builders who want a reliable, affordable module for Arduino, ESP32 or Raspberry Pi projects.
Key features
- Based on the well-known MAX30102 optical sensor chip
- Reads pulse and SpO2 signals for maker and research-style projects
- Small, breadboard-friendly board that is easy to wire
- Works over the common I2C interface with popular dev boards
- Plenty of open-source libraries and example code available
Typical uses
- Arduino, ESP32 and Raspberry Pi learning projects
- Wearable and fitness-style prototypes
- STEM, electronics and IoT classroom experiments
- Graduation projects and hobby data-logging builds
How to choose / tips
- Confirm your board supports I2C and 3.3V logic before wiring.
- Use a stable, clean power source for steadier readings.
- Start with a tested library and example sketch to save setup time.
- This is a hobby/learning module, not a certified medical device.
