Abstract	This study examines the use of an RF-based remote system to manage domestic electrical appliances. The wireless remote control based on an RF technology can toggle the status of equipment to ON or OFF from any site without necessitating a line of sight anywhere around house. The regulating circuit is developed around a 434 MHz operational frequency RF receiver and transmitter module, along with the HT12E encoder and HT12D decoder integrated circuits and a few other passive components. The four distinct channels at the encoder end are used as switches for input signal, and the four channels at the decoder end are used as outputs points, which is connected to the respective electrical devices that are to be controlled; if the appliances are of a higher rating, the relays are used as an intermediary to connect the equipment to the receiving end of the circuit. The transmission method used in this instance is Amplitude Shift Keying (ASK), and the circuit is powered with a 9V DC battery source. The main objective of this task entails creating a closed circuit without any programming knowledge and making it functional without the need for line-of-sight utilizing RF technology. Also, as proposed development to the current working model is stated with a brief description of its functioning, which aims to efficiently control more than four electrical units using the same remote-control technology with the aid of a matrix keypad as input for switching the states of the devices, a matrix encoder & decoder for respective encoding & decoding of signals, and a stable multivibrator for circuit operations.
