Iot Based Patient Health Monitoring System

Abstract: The proposed system is an advanced Internet of Things (IoT)-based health monitoring solution designed to provide continuous and real-time tracking of a patient’s vital parameters.The system is built around the ESP32 microcontroller, which acts as the central processing unit and communication hub. It integrates multiple biomedical sensors, including a temperature sensor, heart rate sensor, ECG sensor, and blood pressure sensor, to collect accurate physiological data from the patient. The acquired data is processed by the ESP32 and displayed on an LCD screen for immediate local monitoring. In addition to local display, the system utilizes Wi-Fi connectivity to transmit the data to an IoT platform, enabling remote access through a caregiver’s smartphone. This allows doctors or caretakers to monitor thepatient’s health condition from any location in real time. The system also incorporates abuzzer for emergency alerts and a manual button that can be used by the patient to signal distress. These features enhance the safety and responsiveness of the system during criticalsituations. By combining sensor technology, wireless communication, and IoT capabilities,the proposed system offers a reliable, cost-effective, and efficient solution for remote health monitoring. It is particularly useful for elderly patients, individuals with chronic diseases, and situations where continuous medical supervision is required.
