Abstract :Currently the power industry, the meter reading has a variety of ways. For example: manual meter reading, IC card prepaid meter, meter reading and other cable. However, they are certain deficiencies and high cost. The most advantageous meter reading program should be a low-cost, easy to use . With the development of wireless communication technology by leaps and bounds in recent years, there has been a low-cost device for wireless networking requirements of the ZigBee technology. ZigBee does have low complexity, low power, low data rate, low cost. Apply it very suitable for modern wireless meter reading system, the meter reading compared to other advantages. Thus this paper discover a copy of the meter based on ZigBee technology solutions.
