RFID BASED DOOR LOCK WITH AUTOMATIC DOOR OPEN AND CLOSE

Abstract

In this paper, we introduce a RFID based door lock with automatic door open and close for Smart door lock system. Currently, our most people use a traditional door lock. Traditional door lock is manual and sometimes it cannot work properly, This traditional door lock open by simply use a replica key also it cannot store any data whose open the door for enter the home or whose come out this home. We were motivated to develop a RFID based door lock with automatic door open and close to overcome these limitations. First we design the RFID Based door lock with automatic door open into PROTEUS software then execute into hardware. The RFID Based door lock with automatic door open based on RFID RS-552 module, Arduino for Processing RFID tags data and PIC 16F877 Microcontroller for use to display who can access or who cannot access. Adding RFID RS-552 at specific to the resisted RFID tag in system that provided information about the authorized user to access into the room and activating the servomotor or when it detect un resisted RFID tag then system active buzzer and servomotor is off condition. Microcontroller (Arduino Uno R3) to receive the on RFID RS-552 signals and process them to the Arduino pins where buzzer and servomotor are connected. We seek in our project to provide a medium cost RFID based door lock with automatic door open and close and suitable for most securable, and also it is light in weight. Our device can detect signal RFID tag within the distance of about 10cm from the user.
