parking gate by ir
ABSTRACT
Wireless communication, as the term implies, allows information to be exchanged between two devices without the use of wire or cable. A wireless keyboard sends information to the computer without the use of a keyboard cable; a cellular telephone sends information to another telephone without the use of a telephone cable. Changing television channels, opening and closing a garage door, and transferring a file from one computer to another can all be accomplished using wireless technology. In all such cases, information is being transmitted and received using electromagnetic energy, also referred to as electromagnetic radiation. One of the most familiar sources of electromagnetic radiation is the sun.
In this project the InfraRed is used to control the parking gate. An InfraRed transmitter is installed in the owner’s car and a receiver is installed on the parking gate. When the owner reaches home, InfraRed transmission and reception will be detected by the microcontroller and it gives the appropriate command to open the gates automatically so the Car can enter the building without any involvement of physical action of human being to open the gates.
