Prototype Design of Smart Diabetic Shoes with Lora Module Communication

Abstract—Diabetes is a disease that affects many people in
the world. Diabetes mellitus is a type of metabolic disease in a
person who suffers from blood glucose levels with extreme
conditions, namely insufficient insulin production in the human
body. Monitoring diabetes is an important concern for
researchers because it can be useful for improving the quality of
the nursing service system. One of the common conditions in
diabetic patients is ulceration which is difficult to detect on time.
Technology can minimize the total cost of monitoring chronic
diseases such as Diabetes continuously and on time. This
research focuses on solutions to produce IoT-based smart
diabetic shoes that utilize pressure sensors and the temperature
of the feet of people with diabetic feet. Smart diabetic shoes are
made using the Lora E32 module to be applied to areas with
poor internet connections. The results of the testing carried out
for 60 seconds in this study succeeded in detecting the area of
the foot that experienced the greatest pressure, which was
located on the rear footrest with a portion of pressure of around
25 – 28% of the total body weight. The patient's foot
temperature increases when the pedestal load is greater. The
Lora E32 module also functions as a media transmitter and
receiver at a distance of 2.2 km in sending sensor data.
