Diabetes currently affects over 422 million people globally. These patients are forced to regularly monitor their blood glucose level by pricking their finger multiple times a day, increasing their likelihood to bruising and infection. This project aims to find an alternative method to monitor blood sugar that is noninvasive using a combination of photoplethysmography and near infrared light. Previous studies have discovered a correlation between the peak value of the photoplethysmogram using a pulse oximeter and the concentration of glucose in a patient¿¿¿s blood. The components of this investigation include an Arduino microcontroller board, a pulse oximeter, and a computer with the Arduino program. Ultimately, a patient should be able to place their finger into a pulse oximeter and determine their glucose level based on the relationship discovered in this study and previous ones alike.
