MAX30100 Heartbeat Sensor

The MAX30100 Heartbeat Sensor Module is an integrated pulse oximetry and heart-rate monitoring sensor designed for health monitoring and wearable applications. It combines two LEDs, a photodetector, optimized optics, and low-noise analog signal processing to detect pulse rate and blood oxygen saturation (SpO₂) through a fingertip or earlobe. The module is compact, low-power, and easily interfaces with microcontrollers such as Arduino, Raspberry Pi, and ESP32 using I2C communication. The MAX30100 is widely used in fitness trackers, medical research, and DIY health monitoring systems.
