AIM:
Design and development of RFID based security access control system.
PURPOSE:
Providing security to organization by allowing authorized persons can protect from unauthorized entries. This will helps for protecting physical properties and intellectual properties. Here we propose solution like RFID based gate security access control system.
DESCRIPTION:
RFID reader (EM-18) Interfaced to Arduino through UART interfaces. L293d connected to Arduino to control gate open and close. Siren controlled by relay which is connected to Arduino digital pin.
WORKING:
Here we have three RFID cards. Two cards are valid and one is invalid. By swiping valid card Gate will be open and after some delay gate will be close. It allows only valid cards. If we swipe invalid card then gate will not open and siren will be ON to alert. All this information displayed on 16X2 LCD display.
