The advancement of Internet of Things (IoT) technology has enabled the development of more efficient and integrated health monitoring systems. This final project aims to design and develop an IoT-based health monitoring device capable of measuring four key health parameters: heart rate, blood oxygen saturation (SpO₂), body height, and body weight. The system utilizes the MAX30100 sensor to detect heart rate and SpO₂, the HC-SR04 ultrasonic sensor to measure height, and a Load Cell combined with the HX711 module to measure weight. The ESP32 microcontroller functions as the main controller that processes and transmits sensor data to Firebase in real-time via Wi-Fi connection. Measurement results are displayed directly on an OLED screen and a web-based dashboard with a simple and informative interface. Based on testing results, the system demonstrates high accuracy, with an average accuracy of 98.83%. This tool is expected to assist individuals in monitoring their health independently and efficiently.
