Projects on password based door lock system using microcontroller april 21 2014 by tarun agarwal 40 comments the basic requirement of security can be achieved by designing electrical or mechanical locks that are designed with one or a few keys but for locking a big area many locks are required.
Automatic door lock system project report.
This is a simple project made with arduino uno r3.
This circuit is mainly used for an interfacing of rfid reader with an arduino.
The aim is to control a door lock without keys but using a smart phone instead.
The automatic door lock system circuit diagram using an arduino is shown below.
Download the project report.
Then for the output it haves push button emergency break glass and the door lock circuit.
The concept of the electromagnetic principle will be use in the project.
This project can be enhanced by connecting an lcd display to display the outputs.
In case the user forgets the both passwords this.
Just thought of making a password based door lock system in which you can enter the password via the keypad.
Smart bt door lock simple arduino.
Advantages of automatic door.
The circuit of this project uses three separate parts namely a reader a controller and door lock.
In the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on.
We surveyed many smart doors locking system.
The door lock circuit is using the electromagnetic principle so for the project that will be builds.
System also includes extra features like adding new users and changing old password etc 1.
The system works using keypad to enter a password to the system.
This paper holds total data about the execution of the proposed system.
If entered password is correct then door is open by motor which is used to rotate the handle of the door lock.
Next for the controller it uses the xp m1000x as a controller.
The project design a rfid based passive keyless entry for automobile door lock application is successfully implemented using rfid communication module with atmel 8051 at89c51 programmed based on embedded system technology.
This simple fingerprint door unlock project using arduino can be very useful for door security forensics crime investigation personal identification attendance system and much more.
It increases the security level to prevent an unauthorized unlocking done by attacker.
