This document describes the development of a portable device that can measure blood glucose, temperature, and pulse oximeter readings using an Arduino. The device uses near-infrared light to non-invasively measure blood glucose levels. It also contains sensors to measure body temperature and blood oxygen levels. The Arduino processes the sensor signals and displays the measurement results on an LCD screen. The data can also be transmitted to a laptop for storage. The goal is to help diabetic patients conveniently monitor their health vitals.
