Ethernet Shield Based Servo Motor Control System for Entrance Security Using Internet

Abstract

Home security is something, that is applicable to all of us and a traditional home security system involves having lock on the door or security guards which can prevent burglary in some cases. This project is aimed to develop a micro controller based control system where a servo motor has been controlled by internet. The servo motor actually controls a security lock for entrance door. The resident can choose to control the door from anywhere which gives security as well as convenience for him. An Ethernet shield has been used along with Arduino Uno microcontroller. Arduino sends appropriate signal to the servo motor which eventually opens or locks the door. The user sends command using particular apps/browser through internet to the Ethernet shield which eventually conveys the signal to the microcontroller. Under this project we have successfully implemented and demonstrated the prototype of this system. This project can also be extended to control other home/office/industrial appliances (using relay).
