Android Password Based Remote Door Opener System

Abstract

Our project aims at remote password based door opener system through an android application. The system tends to
make a secure door opening mechanism such that the door only unlocks when a security personnel opens it by entering the right
password through an android application. The authorized personnel need to be present within Bluetooth range of the door but
need not open the door manually. He just needs to enter the right password through his android application in order to unlock the
door. This is a useful concept in places where the security needs to open gates quite usually or need to operate a door from a
vehicle without needing to get down from it.The command sending functionality is achieved through an android application. The
application provides an interactive user friendly GUI for this purpose.
The android application can be operatedfrom any device running on android OS and uses Bluetooth as a medium for sending
commands.As soon as commands are sent through the android device a Bluetooth receiver is used to receive those commands.
These commands are then sent to the 8051 microcontroller. The microcontroller processes these commands and then tallies the
password to check its correctness. If the right password is encountered it sends command to open the door.
