Security Door Lock System Using Pic Microcontroller

The password is entered by making use of a keypad.

Security door lock system using pic microcontroller.

The major components include a keypad lcd and the controller pic16f877a. This system allows the user to unlock the device with a password. In this project we are going to develop a pir sensor and gsm based home security system. Now lets see how the system is designed to work as a locker.

This article describes the making of an electronic code lock using the 16f877a microcontroller. Let us know how to develop this system step by step. Key this key is meant to initialize the system when the system is turned on the controller will scan only this key and pressing this key will enable. The user can also set his password to ensure better protection.

Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. If you are not familiar with it then i suggest you to go through this interfacing lcd and keypad with pic microcontroller. It can be used to detect any intrusion in houses and offices and send the alerts on cell phones. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system.
