GEOLOACATION

It’s my Summer Internship Project. I really surprise when i hear we can trace location any device without using GPS module only using NodeMCU. Through this we can trace any device .You also surprise how can we trace device using only WiFi . Here are the sort description to understand it.

  • · It’s Scan your nearly all WiFi .
  • · Send this device location to Google using Google API
  • · According to this It’s locate your device location
  • · You have strong network connection for this Project.

Step 1: Parts & Tool

Parts

  • NodeMCU(ESP8266 1.0 12E)
  • USB Cable

Tools

  • Arduino IDE with NodeMcu 1.0 12E Board
  • Google API

Step 2: Find Google API

  • Open Your Browser and type : console.developer.google.com
  • Create a new project
  • After Create a new Project click on credential
  • Click on API Key
  • Your API Key Has been generated
    • For Easily understanding see the following picture |>

Step 3: Setup NodeMCu on Arduino IDE

  • Download Arduino IDE from thefollowing Link :- https://www. Main/Software arduino.cc/en/
  • Add Node MCu board on Arduino IDE
  • For uploading code on NodeMCU youhave to add the NodeMCu board on ARDUINO IDE.
    • GO to file & Preference in Arduino IDE
    • And in Additional Board managersection copy the following link
    • http://arduino.esp8266.com/stable/package_esp8266c...

    • and click Ok

    • The board is downloaded

    • Go to the tools and board and select NodeMCU 1.0 12E

    • See the avobe picture for easily understanding

Step 4: Download ArduinoJson Library

  • Go to the
  • Sketch--> Include Library--> Manage Library

  • Type Arduino Json in search box

  • Download the latest version of ArduinoJson library

  • after downloading library click close

  • Add library from

  • Sketch-->includeLibrary-->ArduinoJson

Step 5: Program

Upload the following program on NodeMCU board. and see your device(NodeMCU 1.0 12E board) location on Serial monitor.

#include<ArduinoJson.h>

#include <ESP8266HTTPClient.h>

#include <ESP8266WiFi.h>

}

// now build the jsonString...
