Development of Smart IoT-based Device for Effective Health Vital Signs Monitoring
Main Article Content
Abstract
Background: An important step towards effective treatment of diseases is early detection. Human bio-signals can be detected and identified for a better understanding of the bodily health status. Five traditional vital signs are of significance in the measurement of human health, which include: heart rate, blood pressure, respiratory rate, blood oxygen saturation and body temperature [1]. In this research, we have developed a wearable Vital Smart System (VSS) with in-built sensors to monitor the user’s vital signs (BT, BP, HR), of which current systems have limitations to achieve.
Methods: For the design of our new VSS, the Dynamic System Design Methodology (DSDM) was used, while the stepwise approach of the Unified Modeling Language (UML) and the Object-oriented Analysis and Design Methodology (OOADM) was applied to develop a more technically robust, cost-effective and portable real time device.
Results: The research produced a wearable, cost-effective health vital signs monitoring device containing an IoT interface (BLE) that connects to smart phones; a GSM interface (SIM900A) relying on AT command framework that accesses defined medical personnel on the network in cases of emergencies; optical health LEDs that alerts the user and enables consistent self-assessment of the user’s health condition.
Conclusion: The developed VSS can ensure effective monitoring and early detection of the user’s health status via an optimization of offline and online cross-interfaces of standalone sensors.
