Abstract
Due to the ageing population and the dramatically increasing of the number of patient or disabled person living alone at home, remote health monitoring has become a critical demand for society, and has attracted the attention of researchers. We implemented an Internet of Things (IoT)–based remote health monitoring prototype using the integration between Xethru Ultra Wide Band (UWB) sensor for data collection and vital sign measurement, Lora protocol for data transmission, Raspberry Pi as gateway for processing, and a server for data storage. In the gateway, the UWB sensor data are processed and cleaned using singular value decomposition (SVD) and Singular Spectrum Analysis (SSA) based algorithm in order to detect and monitor the respiration and heartbeat motion of patient. The IoT based scenario using UWB sensor shows a good ability for older people health monitoring without any obtrusion and privacy violation.
