Continuous blood glucose monitoring is necessary for the management of diabetes mellitus, and this is typically accomplished using intrusive finger-prick techniques, which can be uncomfortable and inconvenient. In order to provide real-time, continuous glucose monitoring in an approachable way, this project suggests creating a non-invasive glucometer that is integrated with Internet of Things (IoT) technology. Without taking blood, the system measures glucose levels through the skin using optical sensors like near-infrared (NIR) spectroscopy. After being processed by embedded devices, the measured data is sent over Bluetooth or Wi-Fi to a cloud platform. Through a web dashboard or mobile application, users and healthcare professionals can access the data, enabling trend analysis, alarms, and improved diabetes control.
