Abstract

The smart buildings consume lot of electricity because lights and air conditioners are used too much. That's why these devices often stay on even when no one is present in the hall. There is a growing environmental concern about the saving of energy so that this signal processing framework is required. By checking if a room is occupied, buildings can save energy by making the space comfortable for people without any disturbances. The system uses sensors to detect people and turns lights and air conditioners on or off as per the movement and heat released from humans. The system operates with minimum response delay ensuring effective framework for smart buildings.
