Description

The MAX30103 is an integrated pulse oximeter and heart rate sensor module designed for wearable devices, health monitoring, and IoT projects. It combines red and infrared LEDs with a photodetector to measure heart rate and blood oxygen levels (SpO₂). Compact and low-power, it is widely used with Arduino, Raspberry Pi, and other microcontrollers for DIY health monitoring projects, fitness trackers, and medical prototypes.
