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.

With a quick development of information technology and electronic engineering, smart electrical devices have been become more and more popular in smart homes. These electrical devices are commonly controlled by the remote control panels in which the control signals from the central processor to the smart devices can be transmitted by many channels such as Bluetooth waves, radio frequency (RF) waves, wifi, Zigbee, etc. [1, 2]
In order to increase the flexibility of remote control panels and reduce the number of RF transmitter modules, this paper has developed a method that integrates the RF transceiver module with the Arduino Ethernet Shield wifi module [7, 12]
Summary
With a quick development of information technology and electronic engineering, smart electrical devices have been become more and more popular in smart homes. These electrical devices are commonly controlled by the remote control panels in which the control signals from the central processor to the smart devices can be transmitted by many channels such as Bluetooth waves, RF waves, wifi, Zigbee, etc. Since each control signal line has different frequencies and transmission distances, the remote control panel should be designed to adapt the requirements of each specific smart home [4, 11].
