Abstract
This thesis presents the design and development of a novel smartphone applicationfor simultaneous health monitoring and alerts for agricultural workers using multiple wearable sensor devices via Bluetooth Low Energy (BLE). The application combines health data from a range of sensors such as an IMU that detects body movement, a pulse oximeter that captures oxygen saturation and heart rate, and a thermometer that measures body temperature. The software framework is built using Jetpack Compose in Android Studio, and it incorporates the MVVM (Model- View-ViewModel) model to provide optimized data flow and robust efficiency. By integrating the Dagger Hilt Dependency Injection framework, we enhance the modularity and maintainability of the developed application. Additionally, the utilization of Kotlin coroutines enables addressing the complexities arising from asynchronous operations, especially with simultaneous BLE sensor connections. A systematic data extraction method for sensors is also presented to integrate commercial BLE sensors into custom applications. Furthermore, the application provides an alert system for workers in agricultural settings. It instantly alerts users through unique auditory and vibrational cues when abnormal health readings are detected. The proposed functions of the application in detecting abnormal health parameters and triggering timely alerts were verified through experimental studies. This research contributes to the field of occupational health by presenting a practical solution for developing an open framework smartphone application for agricultural workers.
