In today's world of rapid changes in technology and new inventions and updates being implemented every second, human beings while running for the bigger concerns are neglecting the trivial aspects which may cause them a fortune if such profligate use is continued. One such example is the reckless usage of electricity. In this paper, we present a Smart Lighting System which aims at curbing this problem using IOT. Internet of Things has captured this era of computing technology. It is made up of advanced technology components that have the ability to transmit, analyze and interpret information and function in accordance to the human behavioral inputs. Here we propose an energy efficient system for lighting up a room based on the occupancy of the room and the intensity of the light using PIR sensors and other components such as LDR and Raspberry Pi. The lighting system of the room is based on a grid format and when a person is in the vicinity or the range of a particular bulb, only then will it be lit. The introduction of Raspberry Pi in the model will also allow monitoring of employee work-patterns. Our proposed system will eliminate the human errors such as leaving the buttons on due to negligence. The advent of such a system will conserve energy, enhance customer service and aid economic development.
