Abstract

Hiking has a dangerous risk of accidents and deaths of hikers. It is caused by health problems, lost, and other accidents. A LoRa-based smart armband was designed to detect hypothermia, hypoxia, and emergencies in hikers based on the above explanation. Furthermore, all activities can be monitored using a web accessed through smartphones or computers. If hypothermia and hypoxia are detected, the smart armband will remind the hiker. The IMU sensor will detect movement orientation and acceleration of the hiker during emergencies to be sent to the hiking post for evacuation. All activity data are stored in a micro-SD for evaluation. From the test results, the armband functioned at temperatures ≤35ºC, air pressure ≤ 560,2 mmHg, and acceleration ≥200 cm/s2. The test results also proved that the armband lasted up to 35 hours
