Abstract
The prevalence of diabetes has been steadily increasing in the past few decades, in particular in low- and middle-income countries. This work develops a non-invasive diabetes monitoring device that is cost effective, stress and pain free which can measure glucose level on the spot. The developed glucose monitoring device consists of three parts; the transmitter section (light source) and the receiver section (photodiode) as well as the processor and the data display section. A Near Infrared (NIR) light is applied onto one side of the ear lobe, while a receiver on the other side receives the attenuated light and then converts the signal into a voltage signal. All these variables are then amplified, sampled, and processed inside the PIC16F877A microcontroller after which the glucose reading will be displayed on the LCD and communicated via the Bluetooth on an android application. From the results obtained, the device has successfully shown that the relationship between the output voltages from photodiode is directly proportional to the concentration of glucose. When the concentration of glucose increases, the output voltage from photodiode also increases. This proved that the concentration of glucose could be predicted using near-infrared light at a wavelength of 1550 nm.
