Keywords:
Glucose, Hemoglobin, MAX30102, Photoplethysmography, Pulse rate, Temperature, DS18B20Abstract
The growing need for continuous, non-invasive health monitoring has driven rapid advancements in technologies capable of tracking multiple vital physiological parameters in real-time. This project introduces a non-invasive multi-vital health parameter monitoring system that measures glucose levels, hemoglobin concentration, pulse rate, and body temperature without the need for invasive blood sampling. The system is built around two core sensing components: the MAX30102 optical sensor and the DS18B20 digital temperature sensor. The MAX30102 sensor utilizes multi-wavelength Photoplethysmography (PPG) to estimate glucose levels, analyze hemoglobin concentration, and monitor pulse rate. It operates by detecting variations in light absorption caused by blood flow and tissue composition, enabling accurate physiological assessments from the skin’s surface. Complementing this, the DS18B20 sensor provides precise and stable body temperature readings through direct contact with the skin, ensuring reliable thermal data. Together, these sensors feed data into a processing unit that applies optical absorption principles and Digital Signal Processing (DSP) algorithms to extract meaningful insights. This approach eliminates the discomfort and risks associated with traditional invasive methods, offering a safer and more user-friendly alternative for health tracking. The system is designed for real-time monitoring, making it ideal for chronic disease management, wellness applications, and preventive healthcare.
