Universal Remote Control Systems for Domestic Devices Using Radio Frequency Waves

In the present scenario, the existent remote control systems focus only on home theatre, which is useful but restricted in its use. The main aim of this research paper is to introduce a blueprint of a universal remote which provides full control to the user for all the devices like lights, fans, air conditioner, security systems, water heater etc in a house. With the use of a radio frequency remote control system, and sensors fitted externally to the devices, the status of each device in the house is known to the user, and they can control all of them from a remote area of the house.
