Abstract #19

This project presents the design and implementation of an ol-based health monitoring system built to provide continuous measurement of essential health parameters; especially heart rate Blood oxygen content (SpO2) and body temperature. The system is centered around an ESP32 microcontroller, which was chosen for its strong processing capabilities and convenient Wi-Fi connectivity that allows real-time data transfer. The system integrates multiple sensors, including MAX30102 for heart rate and SpO2 monitoring, the AD8232 for ECG signal collection, and the DS18B20 for temperature measurement. Health data is displayed on the OLED screen for immediate access. It is also sent to the Blynk platform, which supports external health monitoring by users and health professionals from anywhere. Through out development, projects face technical challenges, such as compatibility issues with sensor libraries and limitations in machine functionality. These challenges led to the initial choice of ESP8266 being upgraded to a more powerful ESP32 module to better support system requirements. Additional obstacles include sensor calibration. Authentication of data and guaranteeing reliable data transfer. This is resolved with detailed failure detection. Sensors calibration and upgrading to compatible libraries. These enhancements help ensure a stable and reliable management solution, all problem were resolved, and the system now works properly.
