Password Based Door Lock System Block Diagram

We are going to use a microcontroller of 8051 family.

Password based door lock system block diagram.

This block gives the entered code signals to the microcontroller. Reading the digital input from keypad. The keypad is an input device that helps to enter a code to open the door. In this password based door locking system project a keypad is arranged to open and close the door.

Password based door lock system using arduino simulino uno schematic diagram read smart phone controlled home automation using arduino the key pad library for the arduino uno available in this link keypad this library is setup to do every function for the keypad. The various functions of microcontroller are like. This is the cpu central processing unit of our project. If another person arrives it will ask to enter the password again.

Block diagram of password based door locking system a. After extending the unlocking process for a fixed period of time the relay energizes and then the door gets locked again. If any unauthorized person enters a wrong password in an attempt to open the door then this system immediately switches a buzzer. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system.

Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. If the password is wrong then door would remain l ock ed enyi.
