Smart Luminance Control System Using Arduino, Bluetooth, and Android for Energy-Efficient Lighting

In today's world, energy efficiency and smart technologies are becoming increasingly important. Lighting is a significant contributor to energy consumption, and traditional lighting systems often lack adaptability to changing ambient light conditions and offer limited remote-control capabilities, resulting in energy wastage and inconvenience. To address this problem, this work proposes an Arduino-based Luminance Control System (LCS) that integrates a luminance sensor, dimmer circuit, relay module, Bluetooth module, and Android device to enhance lighting control and energy efficiency. The system offers automatic light level adjustments based on ambient light conditions, remote brightness control via an Android app, and manual on/off control for flexibility and energy optimization. The technical specifications of the system include a luminance-dependent resistor (LDR) sensor, an Arduino microcontroller, and a triac-based dimmer circuit. Built entirely from the ground up, the proposed lighting system underwent rigorous testing, demonstrating the viability of smart and efficient lighting solutions for various settings. This successful implementation paves the way for significant energy savings and enhanced user control in homes, offices, and beyond.
