Password based door locking system.
Password based door lock system using 8051 microcontroller project report.
Again if another person arrives it will ask to enter the password.
Our digital code lock project is a simple electronic number lock system or an electronic combination lock using 8051 which has a preset 5 digit password stored inside the program the system collects 5 digit user input compares the user input with the preset password inside program and if the user input and stored password matches access will be granted by opening the door with the help of relay for a few seconds and closing it automatically after stipulated time.
These techniques are an integration of mechanical andelectronic devices and highly intelligent.
User can change this password anytime he she wish using a keypad.
The password is stored in the eprom so that we can change it at any time.
The microcontroller based door locker is an access control system that allows only authorized person to access a restricted area the system is fully controlled by the 8 bit microcontroller 8051 which has a 2kbytes of rom for the program memory.
Password based door lock system using 8051 microcontroller final report.
Here at89c51 microcontroller is used and it is an 8 bit controller.
All the processing s will be done by 8051 microcontroller.
Video of the project.
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.
In our diy digital lock system 8051 89c51 89c52 is our intelligent unit.
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.
There are many types technologies available to secure our place like pir based security systems rfid based security system laser security alarms bio matrix systems etc.
Password based door lock circuit design uses five major components a microcontroller a relay a dc motor a 4 3 matrix keypad and a lcd.
Electronic code lock using 8051 microcontorller security is a major concern in our day to day life and digital locks have become an important part of these security systems.
Password based door lock system using8051 microcontrollertraditional lock systems using mechanical lock and key mechanism are being replaced by newadvanced techniques of locking system.
It is a simple embedded system with input from the keyboard and the output being actuated accordingly.
