The MAX30100 is a compact integrated sensor module that combines a pulse-oximetry and heart-rate signal front-end on a single breakout board. It uses optical (LED + photodetector) sensing and communicates over the standard I2C bus, making it a popular building block for makers, students, and electronics hobbyists who want to capture biometric-style signals in DIY prototypes, learning kits, and microcontroller projects.
Key features
- Based on the well-known MAX30100 chip for heart-rate and pulse signal sensing
- I2C digital interface for easy wiring to common microcontrollers
- Small breakout-board form factor that fits on breadboards and project enclosures
- Works with widely available open-source libraries and example code
Typical uses
- Arduino, ESP32, and Raspberry Pi prototyping and learning projects
- Student and graduation electronics projects
- DIY wearable and signal-acquisition experiments
- Sensor-fusion and data-logging hobby builds
How to choose / tips
- Confirm your board supports I2C and the module's operating voltage before wiring
- Keep the optical window clean for stable readings
- Use a known library that matches the MAX30100 to speed up setup
