One of the diseases that could affect diabetic patients is the diabetic foot problem. Unnoticed minor injuries and subsequent infection can lead to ischemic ulceration, and may end in a foot amputation. Preliminary studies have shown that there is a positive relationship between increased skin temperature and the pre-ulceration phase, as a result of friction on surface and peripheral neuropathy in patients. Hence, developer have sensors used specifically for collecting vital data. In particular, we are interested in the measure of the foot–temperature. Since there is a large amount of this type of medical device, we will focus on those used to measure temperature by using thermistor sensors on Arduino circuit, calculated from Steinhart-Hart equation. So in equation, we measured the amount of voltage across the sensor. The voltage required to be measured is through the circuit to allow Arduino to receive voltage signals and record results. The results show a prediction for diabetic patients that notification can improve the diabetic patient’s quality of life.
