Abstract
This dissertation presents the methodology for creating a wearable health monitoring system specifically designed to monitor heart rate and body temperature in real-time. In order to ensure the precise and dependable transmission of health data, the system incorporates the Polar H10 heart rate sensor and the DS18B20 temperature sensor, which are connected to the ESP32 microcontroller. A smartphone application, developed using the Kivy and KivyMD frameworks, enables users to monitor vital signs and receive real-time health information through a user- friendly interface compatible with both Android and iOS operating systems. Evaluation of the system verified the accuracy of the heart rate and temperature sensors. The Polar H10 sensor had a mean error of 0.0 ± 0.5 BPM, which is lower than that of clinical-grade ECG machines. The DS18B20 sensor showed precision with a mean error of ±0.1°C. By leveraging the low-power modes of the ESP32, the system achieved optimal power efficiency. However, the use of Wi-Fi transmission for uninterrupted data transfer presented notable energy consumption issues, underscoring the need for future enhancements in communication protocols. The connectivity testing demonstrated robust performance in unobstructed habitats, but indicated constraints in intricate indoor environments characterized by interference and obstructions. This study adds to the expanding domain of wearable health technology by focusing on important factors related to sensor precision, energy efficiency, and data transfer. Potential future versions could integrate Bluetooth or GSM technology to improve connectivity and investigate supplementary health parameters, such as blood oxygen levels and sleep monitoring, in order to provide a more comprehensive health monitoring solution. Additional clinical validation and rigorous testing are proposed to enhance the system for wider use in both consumer and clinical environments.
Description
This dissertation presents a wearable health monitoring system using the Polar H10 heart rate sensor, DS18B20 temperature sensor, and ESP32 microcontroller for real-time data tracking. A mobile app (Kivy/KivyMD) ensures user-friendly monitoring on Android and iOS. Testing confirmed high accuracy, but Wi-Fi transmission increased power consumption. Future improvements include Bluetooth/GSM integration and expanded health metrics for better usability in clinical and consumer settings.
