The main objective of this project is to develop a smart home automation system with a four button key fob transmitter by using RF (Radio Frequency) technology.
Nowadays, houses are gradually shifting from normal switches to centralized control system, involving a remote control transmitter. This technology is not only easy to use but also helps to prevent missuses of energy. Remote control (key fob) transmitter is small and very light weight, which will work from a decent distance.
It helps elderly people to control switches from anywhere up to 75 feet. This four button key fob transmitter is also very productive for commercial uses in Industrial and medical systems. Remote controlled home automation system provides a simpler solution with RF technology.
In order to achieve this, a RF remote(Keyfob) is interfaced to the microcontroller on transmitter side which sends ON/OFF commands to the receiver where loads are connected. By operating the specified remote switch on the transmitter, the loads can be turned ON/OFF remotely through wireless technology.
Arduino IDE software has been used to compile some programs related to the micro controller ATmega328. (Arduino Uno R3)
