DEVELOPMENT OF A SMART LIGHTING SYSTEM USING VISIBLE LIGHT COMMUNICATION TECHNOLOGY

The development of smart lighting systems has seen a significant increase in recent years, driven by the need for energy-efficient lighting solutions and the emergence of the Internet of Things (IoT). Visible Light Communication (VLC) technology is an emerging technology that uses light waves to transmit data, providing a promising solution for smart lighting systems. This paper presents the development of a smart lighting system using VLC technology. The proposed system consists of a light-emitting diode (LED) lamp that acts as a data transmitter and a photodiode receiver that receives the transmitted data. The system is controlled using a microcontroller and a graphical user interface (GUI) that allows users to adjust the lighting settings. The system uses the modulation of the LED lamp's light intensity to transmit data. The modulation rate is designed to be higher than the human eye's flicker fusion threshold, ensuring that the transmitted data is not visible to the human eye. The system's architecture is designed to provide reliable and efficient data transmission, even in the presence of ambient light. The proposed smart lighting system offers several advantages over conventional lighting systems. First, it provides energy-efficient lighting, as the LED lamp can be dimmed or brightened as per user requirements. Second, it allows for the transmission of data, enabling the system to be used for indoor positioning and other applications. Third, the system is easy to install and use, requiring only a few components. In conclusion, the development of a smart lighting system using VLC technology is a promising solution for energy-efficient lighting and data transmission. The proposed system provides reliable and efficient data transmission, even in the presence of ambient light. The system's architecture is designed to be simple and easy to install, making it suitable for a wide range of applications. The experimental results demonstrate the system's feasibility, and further research could lead to improvements in the system's performance and functionality.
