Password Based Door Locking System Using 8051 Ppt

In this project i am going to design a simple automatic door lock system using 8051 89c51 89c52 microcontroller 16 2 lcd 4 4 numeric keypad and a digital lock.

Password based door locking system using 8051 ppt.

Atmega based garage door opening. User needs to enter the password using an application on android mobile. The main concept behind this project is a door latch opening using a password entered through the keypad. Password based door lock system using 8051 microcontroller traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.

This is an advanced door opening system compared to the above system. In this way a simple door lock system can be implemented with the use of a microcontroller. It can be used in the house shop offices industry. Working of password based door locking system with 8051 when power supply is turned on a message enter your password is displayed on lcd.

The microcontroller based door locker is an access control system that all electronic code lock with user defined password using 8051 microcontroller at89c51. These techniques are an integration of mechanical and electronic devices and highly intelligent. If password does not match door remains closed and a message wrong password access denied is displayed on lcd. To give user more secure yet cost efficient way of door locking system.

Give the flexibility to the user to change or reset the password in case the user forgets that combination. User can change this password anytime he she wish using a keypad. We have provided a relay and a dc motor to give a demo of door lock opening. Password based door locking system.

Objective increase the security level to prevent an unauthorized unlocking of the door. Lock the door by using password. All the processing s will be done by 8051 microcontroller. Android mobile controlled door security locking system has its main application in security systems.

Video of the project. We type the password using keypad which is attached with the system. If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.
