Abstract: Our project describes the tactic of measurement of the glucose concentration and simultaneously hemoglobin within the human blood non-invasively using the painless near infrared-based optical technique. In recent practice, the concentration of glucose and hemoglobin in blood is measured using invasive techniques which generally involve pricking finger (commercial Glucometer and samples using spectroscopy). The frequent finger pricking causes damages on the skin and also increases the danger of spreading infectious diseases. So, the development of non-invasive blood sugar and hemoglobin measurement system are going to be a boon to diabetic patients. The designed system uses Near Infrared (NIR) spectroscopy to work out blood sugar levels supported transmittance spectroscopy emitting signals of 940nm wavelength. These optical signals are sent through the fingertip and reflected signals are detected by phototransistor placed beside. The glucose concentration and therefore the hemoglobin within the blood are determined by analyzing the variation within the intensity of the received signal obtained after reflection. The described system is majorly useful for diabetic patients. In our project, we used Ardunio Uno for the acquisition and processing of the signals. The developed low-cost device could avoid complicated procedures and provides continuous monitoring of glucose and hemoglobin concentration.
