ABSTRACT
In response to the consistent challenge of key misplacement experienced all over the world, the “development of a LoRa-based GPS tracking system for smart keyholders" project introduces an innovative solution that combines Global Positioning System (GPS) technology with Long Range (LoRa) communication. This smart key holder aims to redefine personal asset management by providing real-time tracking capabilities, extended communication range, and energy-efficient operation.
This project utilizes an ESP module, two LoRa modules (sender and receiver), and a GPS tracker to implement a real-time location tracking system for a missing keyholder. The system leverages the GPS (Global Positioning System) to accurately determine the keyholder's current location. The GPS tracker acquires the location coordinates, which are then accessed by a microcontroller and transmitted to show precise locations on the mobile devices via the google maps. The process begins with the GPS tracker capturing the keyholder's location data, which is sent to the first LoRa module. The first LoRa module transmits this information to the second LoRa module, which is then received by the ESP module. The ESP module, utilizing a dedicated application, processes the incoming data from the LoRa modules to extract the longitude and latitude coordinates and show the precise location on the application using google map algorithm. The system is designed to operate continuously and is powered by batteries that are capable of sustaining long periods of operation before requiring replacement. This ensures that the tracking system remains active and reliable, providing consistent location updates as needed.
The tracking system was tested and the results shows across different ranges of 500m, 2600m, 3400m, 5100m from the keyholder, the GPS tracker reliably pinpointed the keyholder's location, which was accurately displayed on the mobile application's interface validating the functionality of the GPS tracker and its integration with the mobile application.The success of this project signals a step forward in the realm of smart personal asset management. The findings and insights gained from the implementation pave the way for future enhancements and applications, emphasizing the adaptability and scalability of the smart key holder concept.
