Design and Implementation of an IoT-Based Healthcare Monitoring System

According to ways-to-die website, over 150,000 people die every day. And the most common cause of death, i.e., about 20% of all deaths, is heart diseases. So, the most crucial contribution from our side to lower this percentage can be to monitor the cardiac values as much as possible. There are conventional methods to measure patients’ health and condition, but they are laborious; have possibilities of errors; and nocturnal monitoring has as well been very difficult. Moreover, since 2019, COVID19 has caused more than five million deaths all around the world, as stated by WHO. And it made the physical presence of doctors and caretakers almost impossible. So, we have designed an up-to-date IoT-based project that continuously monitors the patient's body temperature, heart-rate and oxygen saturation level; keep the data readings in display before the patient and in the screen of the doctor's mobile; and it also provides a non-touching handsanitizing system. The proposed design integrates NodeMCU, DS18B20 Temperature sensor, Max30100 Pulse-oximeter, and other required materials in a small box. The readings are as accurate as the conventional medical equipments while it just takes less than a minute of time to perform the whole procedure. The developed project has outperformed the conventional method by providing a safer, less complex, cost effective and faster service.
