Abstract

Now a day, people venture into extreme outdoor activities such as mount biking, wall climbing, abseiling, jungle tracking and also hiking. Undeniably, everything that we do have its own risky, in this case, we might get lost in the jungle. A year back then, Malaysia have been shocked with news of a runner was named Mohammad Ashraf Hassan, 29, went missing after he joined Gopeng Ultra Trail Run 2019 where the event was held in the jungle trail. Until now, the victim is still missing. Then, there are several other cases about people missing in the jungle but luckily, they were founded safely. The purpose of this project is design as a monitoring system for the rescue team to allocate the position of the missing hikers who lost their tracks in the jungle. This project consists of two main component which are a transmitter and a receiver. Both devices controlled by ESP32 microcontroller that has been equipped with LoRa and GPS based technology, where these devices can connect with a smartphone via Bluetooth for a monitoring purpose later. LoRa is a low power wireless ‘Long Range’ interface developed low data rate cell type communication while GPS is a satellite, receiver and algorithm used by navigation system for synchronizing the location, speed and time data for air, sea, and land movement. With a combination of both technologies, plus, the ideal LoRa for providing fast low-rate data connectivity over significant distances will be the key of the success to this project. Even though, the condition in the forest may produce interference because of the hills and tree, the preliminary result of this project is to received data from the transmitter with a minimum range using LoRa connectivity.
