Enhancing Energy Efficiency and Convenience with an Automated Room Light Control System

Abstract

This paper presents the implementation of a system that controls light automatically and it is energy efficient as it only switches on the lights when required and switches them off when not needed, reducing energy consumption. Furthermore, from past study, it was noticed that most physically challenged people and most aged people do not even have the strength to switch on and off the lights as a result of the inability to manually operate the system. 

For this research the ESP-32 microcontroller which is the heart of the system was used, it is programmed to receive signals from the PIR sensor and switch the lights on when it detects movement in the room. The system is also designed to switch off the lights automatically when no movement is detected for a predefined time period. The light control of the system is actualized when an individual enters and remains off after leaving. The designed system is achieved using infrared light sensor and combination of array counters. The implemented system can be commercialized to be used in public places like malls or libraries to restrict the flow of people.
