Encrypted & Secure Gate Control

Description

This Encrypted & Secure Gate Control kit is being designed to bring the RF technology (range limited wireless communication) in use that is a widely used wireless communication system. It is used in different applications in different forms like security systems, attendance systems, wireless control units, etc.

In this Encrypted & Secure Gate Control system, we are using this technology to make a wireless remote through which we can control the door in a definite range without touching the door. The authenticated user who knows the password will have to send a particular sequence of code (password) from the remote end, as soon as the code matches the door will be opened for a definite time interval and will be closed automatically.

Encrypted & Secure Gate Control has two sections of this system; one is the transmitter end and the other one is the receiver end. At the transmitter end, there is an encoder IC that encodes the 4-bit data and transmits it with a wireless device working at 315/434 MHz At the receiver end RF receiver receives the data with antenna and feeds these data to the decoder IC. The decoder IC decodes the data in 4-bit mode and the microcontroller checks the data sequence with these 4 bits. The display unit is an LCD of 16×2 sizes. It is used for proper user interaction. If the sequence entered is correct the door opens for the person to enter for a while and then automatically closes.
