- Abstract
Purpose: This research aims to construct a low-cost and easy-to-use Internet of Things (IoT) system, so that the elderly population and the physically and mentally handicapped people can get help and assistance at times of emergency. Purpose for this research is to design a fall detection system based on LoRa. Design/methodology/approach: This research adopts the fall detection method of Huynh, Nguyen, Irazabal, Ghassemian, and Tran (2015), using the Arduino Nano 33 Bluetooth Low Energy (BLE) nine-axis sensor with an accelerometer and a gyroscope, two index parameters are extracted from the accelerometer, one index parameter is extracted from the gyroscope. After continuous testing, the index parameters measured by each action were compared, including running, walking and fall down, and finally three thresholds were set. Once the three threshold conditions are met, it is determined to be a fall. The emergency message will be transmitted to the system gateway together with the GPS information of the National Marine Electronics Association (NMEA) protocol via LoRa, and the message will then be sent to the server via TCP/IP communication. Finally, an emergency message is received by the rescuer and a rescue operation can be deployed. Originality/value: The value of this research lies in the application of the optimized fall detection algorithm, which can more accurately determine the fall state. Its innovation is the use of the LoRa communication protocol, which increases and enhances the receiving range and distance. Since this wearable IoT device does not need the mobile phone, the cost is reduced. The device is worn on the body of the target subject and no additional settings are required. The overall transmission applicability is increased with gateways, which can cover a bigger area where the device can work in case of emergency.
