Mountain Climber's Location and Health Condition Detection Device Using Machine-To-Machine Communication

In Indonesia, mountain climbing activity has become more favorable. Anybody interested in this activity must have a basic awareness of mountaineering, including knowledge of the necessary equipment, safety, and mountaineer safety. However, these issues are still unknown to most mountaineers, which can cause hypothermia and loss of track. In this situation, it is crucial to always monitor the health condition and the location of the mountaineer. In this research, the authors designed devices for monitoring the health condition and location of the mountaineers, including the group leader and all participants using machine-to-machine communication via Wi-Fi connectivity. The ESP32 development board was used in this research, the GPS Neo 6M (for location) and DHT11 (for body temperature) sensors. The device was tested in a real environment and actual conditions based on preset parameters, including the location accuracy, the temperature accuracy, and the distance between the group leader and the participants. All the data measured by the devices was sent to the Android application using a local Wi-Fi connection for real-time monitoring purposes. Based on our test, the average accuracy for the location (i.e., the distance) is 99.62%, while the average accuracy for temperature is 99.93%.
