Design of a Non-Invasive Blood Sugar Level Measuring Instrument Using Arduino Nano and MAX30100 Sensor Module

Many electronic technologies are still used in the healthcare field that require a sample of the patient's body to determine the blood sugar level in the patient. Both invasive and non-invasive methods. Invasive methods take blood samples while non-invasive methods use urine samples. For patients who are reluctant to take blood or urine samples to check blood sugar levels, a finger sensor can be used on their fingertips. The purpose of this research is to design an accurate and effective glucose monitoring that is easy for people without fear of needles. This device utilizes Arduino Nano as the main platform and MAX30100 sensor module that is sensitive to glucose molecules in the blood. This research uses the R&D (Research and Development) method and uses the ADDIE approach model. The results of this research show that this device has an average relative error percentage of 5.7%, according to the results of the device comparison test. And the percentage value of the accuracy of this device is 94.3%. On testing the level of feasibility by validators received a final percentage score of 98.3% according to the results of the first validator. This device can be considered "Very Feasible" for use. Results from the second validator showed that the device received a final percentage score of 95%. This device is considered "Very Feasible" for use.
