ABSTRACT
A healthcare monitoring system based on the Internet of Things has been designed to monitor the vital signs of patients with COVID-19 while they are isolated at home. The complete system is designed using an embedded controller, medical sensors, a mobile application, and a cloud server. This Internet of Medical Things (IoMT) device is used to evaluate COVID-19 patients' critical levels during home isolation by monitoring their heart rate, body temperature, oxygen saturation (SpO2), cough intensity counts and geographic position. This approach enables physicians to assess COVID-19 patients without the need for direct contact, thereby minimizing the risk of infection. An embedded hardware device with internet connectivity collects and displays vital signs of COVID-19 patients and transmits the data to an IoT platform. The cloud layer and smartphone application store COVID-19 patient records via the API interface. Additionally, the Hospital Management System (HMS) is utilized to manage physician appointments and the prescriptions given to patients. Mobile applications and email notifications are sent to physicians and patients' families in case of an emergency, allowing them to respond quickly. The users can also view their vital signs and an alert message on the OLED screen. © 2022 IEEE.
