GPS_Tracker

ESP8266 GPS Tracker with Web Interface and SMS Functionality

Overview

This project is a GPS tracker that uses the ESP8266 Wi-Fi module, NEO-6M GPS module, and SIM800L GSM module to gather and transmit location data like latitude, longitude, speed, altitude, and timestamps. The data is sent to a backend server using HTTP, displayed on a web interface, and can also be sent via SMS or missed call to a specified phone number by triggering a button.

Required Components

1. ESP8266 Wi-Fi Module
2. NEO-6M GPS Module
3. SIM800L GSM Module
4. Connecting Wires
5. Power Supply (3.3V for ESP8266 and 5V for GPS and GSM modules)

Circuit Diagram

Connections:

ESP8266 Pin	NEO-6M GPS Pin	SIM800L Pin
D1	D1 (RX)
D2	D2 (TX)
D3		D3 (TX)
D4		D4 (RX)
VCC	3V	3.7v Battery
GND	GND	GND

create a common ground for all the modules.

Note: Ensure proper power supply to all modules. Use a voltage regulator or level shifter as needed for compatibility.

Installing Dependencies

Prerequisites

• Install Node.js from nodejs.org.
• Verify the installation:

  node -v
  npm -v
  

• Install cors

  npm install cors

• To start the server, run:

  node server.js

  or

  nodemon server.js

For ESP8266

• Install the Arduino IDE from arduino.cc.
• 1. ESP8266 Library (ESP8266WiFi, ESP8266HTTPClient, WiFiClientSecure) Open Arduino IDE. Go to File > Preferences. Add the following URL to the Additional Board Manager URLs field:

  http://arduino.esp8266.com/stable/package_esp8266com_index.json
  

  Go to Tools > Board > Boards Manager. Search for ESP8266 and click Install. This will install the ESP8266 core along with the required libraries (ESP8266WiFi.h, ESP8266HTTPClient.h, WiFiClientSecure.h).
• 2. TinyGPS++ Library Go to Sketch > Include Library > Manage Libraries. In the Library Manager, search for TinyGPS++. Install the library by Mikal Hart.
