Implementation of Microcontroller-Based Electrical Room Control System

Abstract

The implementation of a microcontroller-based electrical room control system aims to provide an automation solution in managing electricity usage in a room. This system uses an Arduino Uno microcontroller integrated with a timer to automatically set the on and off time for electrical equipment, such as lights, fans, and computers, according to a schedule determined by the user. In addition, this system is equipped with an SMS notification feature that provides information regarding the operational status of components, such as notifying if a device is not functioning properly or is damaged. The test method shows that this system can set the time accurately, with most tests successfully turning electrical devices on or off according to the set schedule. However, there are several situations where delays or errors in operation occur, indicating the need for further evaluation in terms of timing and system programming. However, the SMS feature makes it easy for users to monitor the status of electrical equipment, so that they can immediately take action if a disruption occurs. The implementation of this system is expected to not only increase the efficiency of energy use, but also help in saving operational costs and managing rooms more efficiently. With automation in electrical control, this system provides comfort and security, and reduces the risk of energy waste caused by uncontrolled use of electrical equipment. This microcontroller-based electrical room control system has great potential to be implemented on various scales, from households to use in commercial and industrial areas.
