Description
The MAX30102 Sensor is a compact module that combines a pulse oximeter and heart-rate monitor in one package. It integrates red and infrared LEDs, a photodetector, optimized optics, and low-noise electronics to measure oxygen saturation (SpO₂) and heart rate accurately. The module communicates via I²C interface, making it easy to interface with microcontrollers like Arduino, ESP32, and Raspberry Pi. It’s widely used in health monitoring, fitness trackers, wearable devices, and DIY biomedical projects.
