Smart fall detection system is developed to detect people’s status in private areas, such as accessible toilets, and prevent delayed treatment. This originated system includes the server and on-site fall detection hardware which are connected by the Narrowband Internet of Things (NB-IoT) technology. The hardware includes a microcontroller unit and two thermal sensors. The server can then calculate the data detected by the thermal sensor and send alert signals to the backend user for abnormal detection.
