Remote AC Power Control by Using Microcontroller

Abstract

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. To improve presence power control technology, this paper presented a phase control method implemented on Arduino microcontroller to control power delivered to AC loads by using TRIAC. In this paper, a lamp load is used as the AC load. Moreover, wireless remote technology based on Bluetooth is used to control the AC loads. 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.  Furthermore, the response of the developed remote AC power control system is compared with a conventional dimmer switch available in market.
