Abstract:
Hypertension, also known as high blood pressure, is a prevalent global health issue affecting over one billion individuals worldwide[1]. It serves as a major risk factor for cardiovascular diseases, including heart attacks, strokes, and kidney failure[2]. In many regions, especially rural and underserved areas there are challenges associated with monitoring and managing non-communicable diseases(NCDs) including regular check-ups and consultations with healthcare professionals. Traditionally, individuals would have to use separate devices to measure their weight and blood pressure, which can cumbersome and time consuming. This thesis presents the design of a smart scale equipped with an integrated sphygmomanometer based on the Internet of Things (IoT) for hypertension monitoring and risk assessment. The proposed system combines weight and blood pressure data collected by the smart scale to effectively monitor and track hypertension progress. Early detection and management of hypertension are essential for preventing these complications. In designing a smart scale with integrated sphygmomanometer based on IOT develop a smart scale that can measure weight, height and blood pressure, it stores and transmit data to a cloud platform, it generates personalized hypertension monitoring status, and provide real – time hypertension risk assessment. The smart scale utilizes a load cell sensor for weight measurement, a blood pressure cuff for blood pressure measurement, and ultrasonic sensor for height measurement. These sensors are connected to a microcontroller unit (MCU) to collect, process it and to send the processed data to the cloud server, a cloud server to store the user's data and make it accessible to authorized medical professionals. This project allows for the monitoring of patients' health in remote or rural areas without access to medical care. A smart scale with an integrated digital sphygmomanometer based on IoT could be a valuable tool for preventing and managing hypertension in rural areas. This device would allow people to monitor their blood pressure and weight at home, and to share this data with their healthcare provider remotely. The development of this smart scale was carried out over a period of two years. The research involved extensive literature review, system design, prototype development, testing, and evaluation.
