Authentication and Centralized Control of Electrical Devices Using Zigbee Protocol

In buildings, lighting accounts for more total energy cost, reducing this energy consumption is a major goal of this project. Energy reduction comes from turning off lights when they are not needed, optimizing light levels to suit worker needs. Through the use of modern enterprise-class wireless networking technology, the difficulty of control wiring is eliminated. In this project, the analysis, design and implementation of an intelligent office room whose two main components are realized using two emergent wireless technologies, namely, wireless sensor networks (ZigBee) and Radio-frequency identification (RFID) tags. The combination of these two technologies produces a powerful and versatile solution that can offer automated access control to an office room as well as the monitoring of entry or exit of an employee and also to perform automated job as described in the profile
