Abstract:
Remote control switching device for household application is a home device used to control the switching of household appliances from a distance. It serves to make the switching of household appliances easy for the elderly, physically challenged, the young and anyone who, in any circumstance, needs comfort and security. This paper develops a remote control system using the Radio Frequency technology utilizing multiplexers, demultiplexers, encoders, decoders, and Radio Frequency module with the analysis of various technologies which can be used for the development of a remote control system. A security system is incorporated in this remote control to provide a secured usage of the system from a distance of about ten meters away. To achieve the aim of this work: a transmitter system is design and constructed which processes and sends out signal when a button is pressed; the construction of a receiver system which receives and processes the signal from the transmitter system, then turn on or turn off the appliances; and incorporate a security system which allows transmission of signal only when certain condition is met. Avoiding the use of microcontroller, this paper developed an affordable, reliable and effective remote control system for household applications
