Abstract

Nowadays, AC power control has becoming a common issue relates to the energy efficiency. The drop in efficiency mostly because of electrical energy consumed by the electrical devices. AC power control can be controlled by adjusting the desired level of output power of the electrical device. The present technology is able to feedback the ambient light intensity to adjust the require output power deliver to the light by using sensors. Although the present technology is mostly designed with self-controlled system, but are these devices really can give the desired output power to achieve the higher efficiency. Hence, the solution to solve this issue is to control the electrical appliances with Bluetooth signal. The electrical appliance is control manually by using Bluetooth device. Furthermore, disabilities they need this device to control the desired output power. The development of AC power control using smartphone via Bluetooth is designed with the microcontroller to adjust the servo motor and the motor is attached to the potentiometer which can adjust the output voltage deviate from 240V to the load. The servo motor as the mechanical way to control the potentiometer is because the motor and the electronics components could not withstand as much 240V from the source. Therefore, the output voltage to the load is able to control at voltage range of 0V - 240V. The servo motor will only rotate when the Bluetooth signal from smartphone is sent to the Bluetooth device which connected to the PIC microcontroller. The software for the smartphone to control the Bluetooth signal is designed by the MIT Apps Inventor (Android-based only).
