Design of Low Cost IoT Assisted Remote Health Monitoring System for Diabetes

Abstract

The human race world over has been facing unprecedented challenges of pandemics with viral and bacterial microorganism mutations. One such unprecedented virus outbreak over last few years was Coronavirus disease (COVID) which completely changed human perceptions and global response mechanism for such kind of future possibilities.  It is of infectious nature and caused by the SARS-CoV2 virus. This virus first emerged in humans in China and quickly spread to other countries, affecting human existence throughout the world. The whole of humanity including engineers, scientists, and medical professionals joined forces to fight against this virus. Although the collective efforts succeeded in controlling the outbreak ultimately but the capacity of virus to quickly evolve and change its variants sustained its various mutations. Further, the restricted movement of people to stop the spread of COVID personal visits to the medical practitioners got affected severely.  This further affected people with ailments like diabetes and studies have shown that diabetic people are more severely affected by the COVID. The large number of diabetic people worldwide has necessitated the continuous monitoring of patients through remote monitoring mechanisms using invasive and non-invasive methods of measuring sugar levels. Invasive glucose monitoring involves risk of infection at home. This paper presents the scheme for remote health monitoring of the diabetic patients with non-invasively methods coupled with internet of things (IoT) mechanism to assess glucose levels, heart rate and oxygen levels so that the information can be relayed to medical expert at remote location. The level of glucose is measured using PPG (photoplethysmography) signals.
