Abstract
Diabetes is a prevalent condition that affects millions of people worldwide, posing significant health risks if not properly managed. This project aims to develop a non-invasive blood glucose monitoring device, offering a convenient and safe alternative for diabetic patients. By utilizing the conductivity mea- surement technique through the penetration of NIR rays, blood glucose levels are estimated based on the pulse rate and respiration rate. The setup involves an Arduino UNO microcontroller, electrodes for measuring conductivity, and a potentiometer to convert the analog signal to digital voltage. The Arduino UNO incorporates an interpolation equation to establish the relationship between voltage and glucose levels, displaying the results on an LCD display. By com- paring the obtained glucose value with the normal reference blood glucose range, the device can determine if the patient’s glucose level is normal, high, or low. This technique proves to be time-efficient and cost-effective, reducing pain and minimizing the risk of infection associated with invasive methods.
