Abstract

The study aimed to develop a low cost control system for electrical loads utilizing wireless
technology. It dealt with the design, construction, and transmission and reception accuracy analysis of the
SMS, Wi-Fi and Bluetooth technology involved. The design and construction were based on wireless
communication principles and their respective technology applications utilizing electronic circuits,
module/boards, components and devices for signal and data transmission and reception. A pre-programmed
communication apps were properly sketched and installed in a mobile phone and computers to establish
exclusive wireless communication between the transmitter and receiver module of the system. The system
allows multiple electrical loads be controlled from different distances or locations at any time of the day. Trials
and revisions were implemented to have immediate solution to technical issues and problems being met during
the construction stage. The developed control system having the SMS, WiFi and Bluetooth components were
all found very much accurate in terms of signal sending and receiving to switch on and off electrical loads
considering the time, distance and location respectively. T-test result showed that the system’s accuracies with
respect to distances and locations for each wireless system were all synonymous for having a no significant
difference result. From the findings, it was proven that the developed control system can control wirelessly
any electrical loads from anywhere at any parts of the day and may provide home security by avoiding house
fire incidence due to overloading and short circuits. It can also be used to minimize electricity consumption
