RFID BASED SECURITY SYSTEM

WHAT IS RFID BASED SECURITY SYSTEM?

To develop a wireless system to detect and allow only the authorised persons based on the RFID technology

Power section

In this section we used step down transformers of 230v primary to 9v secondary.

The stepped down voltage is then rectified by 4 IN4007 diodes then it gives the i/p to LM7805.

This gives a constant value of 5v DC.

Circuit Discription

To design a RFID Security System There are few steps
That has been performed.

Designing the power supply for the entire circuitry.
Selection of microcontroller that suits our application.
Selection of RFID cards and reader.
Selection of MAX232.
Selection of LCD
