ZigBee Technology

In this paper describes the design and implementation of a wireless smart home using ZigBee technology. The Microchip Picdem Z development kit hardware forms the base from which a network coordinator, temperature sensor and light sensor are designed. These devices were implemented directly on the Picdem Z board�s prototyping area. We use Microchip�s Stack for ZigBee, MPLAB IDE and C18 compiler to transport data between nodes. This interface allows a user to change the state of an appliance or view the current status of sensors from within the home or from a remote computer. Despite the fact that the local interface was not completed, remote control and monitoring Analysis of the design shows that a star network topology is insufficient to provide coverage throughout a home. In addition, analysis shows that household sources of 2.4 GHz radiation do not prevent the network from functioning.
