Low-Cost Health Monitoring System: A Smart Technological Device for Elderly People

Smart and combined medical care to individuals or a community is one of the most demandable implementations enabled by the Internet of Things (IoT). It is feasible to gather exactly instructive symptoms of one's corporal health using different wearable or wireless sensors in our livelihood surroundings. There is a crying need for an IoT-based health monitoring system to continuously monitor the health conditions of elderly people both in the countryside and metropolitan areas. As a result, visiting doctors for regular check-ups is minimized and doctors can save many lives by providing valuable services for emergency purposes. In this research, a prosperous method has been introduced for modified healthcare assistance and implement the system as a prototype. The proposed system collects data from a patient's body using different sensors like ECG sensor, pulse oximeter sensor and temperature sensor and addressed it to the cloud where it is schemed and tested. A video surveillance camera has also been used here to continuously monitor a patients' movement. For emergency health assistance, if any kind of abnormalities is found in a patient's body a pre-programmed email has been sent to the authorized doctors or persons to examine the critical conditions of a patient and prescribe to solve severe health issues. The prototype of the proposed system for health monitoring in outlying areas has been built to manifest its performance advantages and the result shows that the system is efficient for remote health monitoring. This system can be the best example to use in pandemic situations like COVID-19.
