A Room Light Controlling System Based on Curtain and Occupants’ Motion: A Conceptual Study

Abstract

The Internet of Things (IoT), which allows multiple devices to be connected via the Internet, has been widely used in various fields including residential. It is very popular nowadays as it could automate home and electrical appliances without human intervention. This leads to the existence of a smart home. By automating devices at home, electricity consumption can be saved and used at an optimum level. Hence, this paper aims to contribute to the solution of saving energy consumption by deploying a low-cost modular system, that controls lights based on input parameters such as the room’s brightness, occupants’ presence, and motion. The proposed design uses three main sensors such as load cell sensors, motion sensors, and photoresistors. The load sensors are used to detect the occupant’s weight on the bed, the motion sensors are to detect the presence of an occupant, and the photoresistors are used to detect the room’s brightness. Besides, the proposed design is recommended to be integrated with any suitable intelligent system, such as back propagation neural network, to learn occupants’ sleeping patterns. Finally, this work is hoped to lead in light related studies for energy saving.
