System Architecture Overview This project implements a portable biometric monitoring device centered around the STM32F103C8T6 microcontroller. The system integrates both photoplethysmography (PPG) and electrocardiography (ECG) sensing technologies to provide comprehensive cardiac health monitoring....

Sensor Operating PrinciplesThe MAX30102 integrates two LEDs (red at 660nm and infrared at 880nm) and a photodetector to facilitate photoplethysmography (PPG). Blood oxygen saturation (SpO2) is determined by the differential absorption of light by oxygenated hemoglobin (HbO2) and deoxygenated hemoglo...
