A noninvasive blood gluco se measurement system by arduino and near-infrared

This paper proposes a new hardware system to measure the blood glucose concentration. This system has the characteristics of noninvasive, simple and quick. Firstly, we use near-infrared light irradiation fingers. The infrared light transmittance can receive a signal about the blood glucose concentration. Then after an amplifier amplification, this signals will transmit to the Arduino. We use the Arduino Uno board as the CPU to analysis and processing the signal. Through comparison with the standards set, our system can determine blood glucose concentration of the measuring signal. Finally, the results will show on the LCD screen, and it can transmission to a phone or laptop for storage via Bluetooth at the same time. It is convenient that customers to know their changing trends in blood glucose levels. Patients will try to take measures to control the adverse effects caused by high blood glucose when they know their blood glucose levels.
