IoT-Based Temperature, Heart Rate and SpO₂ Monitoring System Using ESP32

The IoT-Based Patient Health Monitoring System Using an ESP32 Web Server is designed to monitor a patient's vital health parameters in real time using Internet of Things (IoT) technology. The main objective of this project is to provide a simple, efficient, and cost-effective system for monitoring patient health and displaying the collected data through a web server. In this system, the ESP32 microcontroller acts as the main processing unit and connects to the internet through its built-in Wi-Fi module. Sensors such as a heart rate sensor, body temperature sensor, and SpO₂ sensor are used to measure important health parameters, depending on the selected hardware configuration. The measured data is processed by the ESP32 and displayed on a webpage that can be accessed using a smartphone, laptop, or computer connected to the same network or an appropriately configured internet connection.
