Abstract : This paper presents the design and implementation of an Automatic Room Light Controller with Bidirectional Visitor Counter using an Arduino-Nano microcontroller. The system aims to automatically control the electrical lighting of a room based on the number of people present. It employs infrared (IR) sensors to detect entry and exit movements, with the count displayed on an LCD screen. When the first person enters, the light turns ON, and when the last person leaves, the light turns OFF automatically. This helps to minimize energy wastage and promotes efficient electricity usage. The system is built using cost-effective electronic components, providing a reliable and smart solution for automatic lighting in homes, classrooms, and offices.

Keywords : Automation, Energy Conservation, Reliable and Smart Solution for Automatic Room Light.
