Raspberry PI 3B+Based Smart Remote Health Monitoring System Using IoT Platform

A portable smart health monitoring system with remote access to the physician is very essential for senior citizens and rural healthcare personnel. This can be achieved by a low-power, accurate, compact, cost-effective, user-friendly system which is capable of measuring the patient's vital parameters. These data are displayed locally at the patient-end and also regularly sent to the physician-end using the IoT platform. The proposed system uses noninvasive sensors tomonitor the vital parameters like heart rate, SpO(2), and body temperature accurately. Raspberry Pi 3B+ minicomputer is used to integrate, process the sensors' data, and remotely communicate to the hospital(s) or the physician using MathWorks cloud and applet. The reliability of the uploaded vital parameter(s) is also verified with the locally displayed data. The use of Webhook applet to notify the physician about the health condition of the patient makes the proposed system novel.
