Build GPS Tracker Using ESP32 and Visualize Data on Map

This project shows how to create a GPS tracker using an ESP32 and NEO-6M GPS module. The tracker reads your current location and displays it on GeoLinker API, its a free API at Circuit Digest Cloud. It is a good starting point if you're interested in IoT or location-based tracking systems.

What is GPS Tracker

A GPS tracker is a device that uses satellite signals to determine the real-time location of a person, vehicle, or object. It is commonly used in navigation, safety, and tracking systems, and can be easily integrated into IoT projects using modules like the NEO-6M and ESP32.

How This Device Works

This project uses an ESP32 and NEO-6M GPS module to create a simple GPS tracker. The ESP32 sends location data to the GeoLinker API via HTTP, where it is plotted on a live map. It also stores data offline when there is no internet and syncs it once the connection is restored.
