[Unpublished undergraduate research project]. Busitema University.https://bdears.busitema.ac.ug/handle/123456789/8599Undergraduate Research final ReportAccess to timely health monitoring is limited in rural areas like Busia District, where patients with chronic conditions often face delays in diagnosis and treatment due to limited medical personnel, lack of diagnostic equipment, and unreliable internet connectivity. This project aims to develop a low-cost, IoT-driven wearable device capable of continuously monitoring essential vital signs, including heart rate, oxygen saturation (SpO₂), blood pressure and the body temperature. The system incorporates a real-time alert mechanism that notifies doctors or caregivers when abnormal readings occur, ensuring prompt intervention. Requirements for the system were identified through stakeholder consultations and literature review. A prototype wearable device was designed and integrated with Wi-Fi connectivity to support both online and offline operation, addressing rural infrastructure challenges. Field validation was conducted in local healthcare settings to evaluate accuracy, usability, and reliability. Results indicate that the device can effectively monitor patient vitals, provide timely alerts, and operate sustainably in low-resource environments. This system offers a practical solution to improve patient care, reduce preventable complications, and enhance health outcomes in rural communities.enOther
