Abstract

Many innovative gadgets or products are introduced to improve human lifestyle, e.g. Smartphone which is one of the important inventions in early 21st century. The early 21st century brings hundreds of thousands of smartphone applications (apps). The built-in features inside a smartphone have made it a device with almost limitless applications. AC power control is already existed in our daily lifestyle but there are some limitations for presence control technology, such as some AC power control devices could not control remotely and provide limited power controlling range. . There are many AC power control technology implemented are wired, users are required to get near to the machines or control panel to control. To improve presence power control technology, this project implemented a phase control method implemented on Arduino microcontroller to control power delivered to AC loads by using TRIAC. Moreover, wireless remote technology based on Bluetooth is used to control the AC loads. Also, controlling machines wirelessly will decrease the chances users get electrical shock, hence improve safety. In this project, lamp load and induction motor are used as AC loads. Furthermore, an Android application (app) is written and ready to install in Android smartphone. Thus, users are able to control the AC loads with a Bluetooth enabled smartphone as graphical user interface (GUI). This system has provided a convenient solution to control AC load wirelessly which required only a smartphone as GUI. Moreover, the response of the developed remote AC power control system is compared with a conventional dimmer switch available in market.
