This project is an IoT-based GPS Tracking System designed to collect real-time location data using an ESP32 microcontroller and a GPS module. The system reads geographic coordinates from the GPS module and can transmit location information to a mobile or web application for monitoring and tracking purposes.
Goal
To develop a reliable IoT-based GPS tracking system capable of obtaining and transmitting real-time location data using ESP32 and GPS technology.
Technologies Used
ESP32
GPS Module (e.g., NEO-6M)
Arduino IDE
C/C++
IoT
Serial Communication (UART)
Problem Faced
GPS Connectivity Challenge
One of the main challenges was establishing a stable GPS connection. The GPS module struggled to obtain a satellite fix when used indoors or in obstructed environments.
Issue: The GPS module only worked effectively when placed outdoors with a clear line of sight to the satellites, causing delays in receiving accurate location data during testing.
Solution
To solve this, I conducted testing in open outdoor environments where the GPS antenna had a clear view of the sky. I also improved the system by adding logic to wait for a valid GPS fix before processing or transmitting location data.
Result: The tracker was able to acquire satellite signals more reliably and produce accurate real-time coordinates once a valid GPS fix was obtained.
