The MAX30102 Heart Rate and Pulse Oximeter Sensor Module is a high-performance biomedical sensing module designed to measure pulse rate (BPM) and blood oxygen saturation (SpO₂). It uses integrated red and IR LEDs, a photodetector, and a low-noise analog signal processing circuit to provide reliable physiological data.
Its I²C digital interface makes it simple to connect with microcontrollers like Arduino, ESP32, STM32, and Raspberry Pi, making it popular in wearable devices, health monitoring projects, and IoT-based biomedical applications.
This module is widely used in fitness trackers, smart healthcare prototypes, academic projects, and IoT-based health systems, thanks to its low power consumption and compact black PCB design.
