📍 Real-Time GPS Location Tracker with ESP8266 & Firebase

A lightweight and accurate real-time location tracking system using U-Blox Neo 6M GPS module, ESP8266 NodeMCU, and Firebase Realtime Database. It continuously pushes live latitude and longitude data to Firebase—ideal for location-aware IoT projects, asset tracking, or DIY geofencing experiments.

🔌 Circuit Connections

GPS Module Pin	ESP8266 Pin
VCC	3V3 or Vin
GND	GND
TX	D7 (GPIO13)
RX	D8 (GPIO15)

⚠️ Note: The GPS module communicates via serial. SoftwareSerial is used to avoid interfering with ESP8266’s default serial port.

☁️ Firebase Setup

1. Go to Firebase Console
2. Create a new project
3. Navigate to Realtime Database > Create Database
4. In "Rules", allow read/write temporarily:

   {
     "rules": {
       ".read": true,
       ".write": true
     }
   }
   

5. Grab your:

• Database URL

• Secret / API Key (if needed for authentication)

6. Insert these into your .ino file where required

📡 How It Works

• The Neo 6M GPS module locks satellite coordinates.

• The ESP8266 reads the GPS data via SoftwareSerial.

• Latitude and Longitude are parsed from the NMEA sentence.

• The data is sent to Firebase in real-time.
