Hemoglux Monitor: A Non-Invasive Glucose, Hemoglobin, and Pulse Monitor

Diabetes mellitus is a chronic metabolic disorder that requires regular monitoring of blood glucose levels to prevent severe health complications. Traditional glucose monitoring methods, such as finger pricking, cause discomfort and increase the risk of infections, which can hinder long-term management. This paper introduces the Hemoglux Monitor, a non-invasive device designed for real-time monitoring of glucose, hemoglobin, and pulse rate using Near-Infrared (NIR) spectroscopy and an ESP32 microcontroller. The device uses a 940 nm NIR LED and a photodiode to measure glucose levels through light absorption and reflection, transmitting the processed data wirelessly via Wi-Fi and Bluetooth to mobile devices for remote monitoring. Real-time glucose measurements are displayed on an internal LCD and continuously monitored via a mobile app. The system was evaluated on 10 participants, achieving an accuracy of 91.5%, with a mean absolute error (MAE) ranging from -7.2 mg/dL to 7.2 mg/dL compared to traditional invasive glucose meters. By eliminating the need for needle-based blood sampling, the Hemoglux Monitor provides a painless, cost-effective solution for diabetes management. The device integrates IoT and edge computing technologies to enhance data processing and enable continuous, remote health monitoring. The Hemoglux Monitor represents a significant step toward improving diabetes care through non-invasive technology, offering potential benefits for both clinical and home use.
