Abstract
Minimizing the unnecessary usage of appliances is the great task that has to be met in this current world. Reducing energy demand in the residential and industrial sectors is an important challenge in day to day life. In particular, in closed area like auditorium where many number of lights and fans will be present it is necessary to stop the working of unwanted appliances. Light-Emitting Diode (LED) lights are more efficient than traditional lights. This project proposes a low cost, wireless, easy to install, adaptable, and smart system to automatically adjust the light intensity and fan speed to save energy and maintaining user satisfaction. The system combines motion sensors and light sensors in a low-power wireless solution using Zigbee communication. This proposed system aims at automatic dimming of light and adjustment of fan speed based on the surrounding and presence of people at that particular area.
