Diabetes affects millions of people globally due to improper healthcare management. The invasive method is arduous for periodic measurement to all age groups; therefore a huge demand arises for developing a sustainable non invasive technique. This paper proposes a simple, non invasive technique for measuring the range of glucose level by Near Infrared spectroscopy and the then data is acquired using Arduino Due board. This is one of a kind approach for finding the glucose range with decision tree algorithm in MATLAB 2013a and the results are validated with the test obtained from Medzon Diabetes center. © Research India Publications.
