The vehicle tracking systems are designed for tracking the movement of a vehicle from a location at any time. Such system is equipped with a GPS receiver which maintains the GPS location of the device. The GPS location of the device traced by the GPS sensor is sent to a cloud server or cloud service with the help of a controller. This project is a simple implementation of such system on one of the most popular prototyping boards – Arduino UNO.  

ESP8266 is a UART to WiFi module which provides an easy solution for connecting any small Microcontroller platform like Arduino to Internet wirelessly. Since ESP8266 super cheap, and super easy to work with it become one of the leading platforms for the Internet of Things. You can use AT commands to connect to WiFi networks and open TCP connections without running TCP/IP stack. It also includes 32Bit Microcontroller which can be programmed to act as a standalone WiFi connected Embedded Platform.
