An Improvement of Remote Control Panel for Numerous Electrical Devices in Smart Homes Using RF and Wifi

Abstract

This study aims to improve a remote control panel for numerous electrical devices in smart homes using radio frequency (RF) and wifi. In this study, RF315MHz transceiver module and Arduino Ethernet Shield wifi module are combined by a programmed algorithm to transmit control signals from a central processor to the electrical devices in the smart house. The RF315 MHz transceiver with hard coding is modified to be a soft coding module in which each control channel can switch on/off 256 electrical devices. Then, a remote control panel is developed to control numerous electrical devices based on the requirements of the number of control buttons and the technology in the smart house. Moreover, this proposed method allow to control the electrical devices in the house by various panels. An experimental model with two separate transmission channels using two soft-coded RF315MHz modules has been done to verify the applicability of the proposed method.
