Modern Energy-Efficient Living: Development of A Sound-Responsive Smart Lighting System

This research developed a Sound-Responsive Smart Lighting System, enhancing home automation and energy efficiency. Utilizing an Arduino Uno R3 microcontroller, an ACE6467 microphone sensor, and an ACE6363 5V relay module to operate a 220V bulb. The authors developed the control logic directly within the Arduino Integrated Development Environment (IDE), creating a program that processed acoustic signals and converted them into digital commands to toggle the light’s state. The primary objective was to enhance accessibility for individuals with limited mobility while reducing the reliance on physical contact for device operation. Systematic testing was conducted in a controlled indoor environment to evaluate the performance of various auditory triggers, including claps, finger snaps, and object tapping, across distances ranging from 0.5 to 2.0 meters. Experimental results indicated that the system achieved “Excellent” responsiveness when triggered by a single clap up to a maximum effective range of 2.0 meters. However, performance significantly declined with higher-frequency sounds like snapping or tapping at distances beyond 0.5 meters, revealing limitations in sensor sensitivity and environmental noise interference. The study concludes that while the Arduino-based Sound-Responsive Smart Lighting System is a highly effective tool for modern home automation, future iterations require more advanced sound-processing algorithms to further optimize energy conservation and minimize false triggering. This research serves as a technical blueprint for cost-effective smart home technology and a foundation for future advancement in sensor-based systems.
