MAX30100 Pulse Oximeter Heart Rate Sensor Module

The MAX30100 Pulse Oximeter and Heart Rate Sensor Module is an integrated biomedical sensor module designed to measure heart rate (BPM) and blood oxygen saturation (SpO₂) using the photoplethysmography (PPG) principle. It combines red and infrared LEDs, a photodetector, optical components, and low-noise signal processing circuitry in a compact module. The sensor communicates through the I²C interface, allowing easy integration with microcontrollers such as Arduino, ESP32, STM32, Raspberry Pi, and PIC. It offers high measurement accuracy, low power consumption, and reliable real-time monitoring, making it suitable for wearable and portable healthcare devices. Due to its compact design and efficient performance, the MAX30100 Sensor Module is widely used in patient monitoring systems, fitness trackers, wearable health devices, biomedical instrumentation, IoT-based healthcare applications, and medical research projects.
