ABSTRACT:

A ZigBee energy management system is proposed in this paper. The system is developed based on wirelesssensor network technology. The developed system is low cost and robust and fully takes the advantages ofZigBee. Environmental sensors embedded with ZigBee router modules are distributed to different locations to collect the environmental data. With collected data and preset energy quota, the control unit of the proposed system updates the status of each electrical appliance in order to minimize the energy consumption. To evaluate the performance of proposed system, a simulation model is developed. It is found that the proposed system saved up 11% and 18%of energy when the saved energy target is 10% and 15% respectively. Such system is the first of its kind in the market.
