A Portable IoT-Based Health Monitoring Framework Using ESP32 for Isolated and Home-Based Patient Care

The creation of an affordable Internet of Things (IoT)-based patient health monitoring system with the ESP32 microcontroller is shown in this study. In order to measure critical factors including blood oxygen saturation (SpO₂), heart rate, and body temperature, the system incorporates biomedical sensors. Real-time data collecting is carried out, and the outcomes are shown on a web interface that is hosted by a companion mobile application and the ESP32's integrated web server. It is appropriate for remote health monitoring applications, including patients in remote areas like homes or special wards, because of its design, which places an emphasis on price, mobility, and ease of deployment. When crucial health thresholds are crossed, the system's alert systems let medical experts know via smartphone notifications and web pop-ups, allowing for prompt medical intervention.
