Model of a Home Patient Monitoring System With An Alert Systems Using Blynk

Abstract

This paper introduces a home-based health monitoring system tailored for elderly patients who face challenges attending regular physical checkups. Designed for non- hospitalized individuals receiving care at home, the system tracks vital health metrics such as heart rate and oxygen saturation, and includes a push button for emergency alerts. Using a prototype methodology, biomedical sensors capture data that is displayed in real time via the Blynk IoT platform, while simultaneously being stored in an Excel worksheet to maintain long-term patient history. When the alert button is pressed, immediate notifications are sent to the caregiver’s smartphone and email, enabling swift response. The system aims to address accessibility barriers in traditional healthcare by offering continuous monitoring, timely alerts, and a reliable data storage framework that empowers caregivers and improves safety within domestic care environments.
