Here´s how is utilized

The IOT platform plays a crucial role in this research by providing a robust and user-friendly interface for real-time data visualization and monitoring.

  • Real-Time Data Transmission 📍: The life jackets GPS module transmits the coordinates via the LoRa module to the receiving station. An ESP32 microcontroller connected to the internet via WiFi uploads the data to the cloud platform.
  • Data Buckets ➡️ : All raw data recorded by the life jacket is displayed and stored in data buckets on Additionally, This allows researchers to download the data in .csv format for detailed analysis.
  • Live Mapping 🗺️: live map feature displays the real-time location of the life jackets. Tracking the life jacket’s movement live is crucial during rescue operations, as long as it transmits data.
  • Dashboard Customization 🎨: Researchers can customize dashboards to present data in various formats, making the information easily interpretable. This includes graphical representations and real-time updates, enhancing decision-making during emergencies.

This research shows that combining LoRa and can greatly enhance marine safety for small-scale fishermen.


This study utilized a LoRa-based long-range tracked life jacket instrument with a GPS module to obtain and subsequently transmit coordinate positions. The results show that RSSI weakens with distance and obstructions like trees, suggesting LoRa suits marine areas without surface obstacles. The LoRa module successfully reached a maximum distance of 12,983 meters, while future research aims to develop smaller instruments with custom antennas to maintain transmission capabilities.

This research demonstrates the potential of combining LoRa technology with the robust capabilities of to significantly improve marine safety for small-scale fishermen.
