ZigBee Sensor Network for Advanced Metering Infrastructure

Introduction of embedded:
Embedded system debugging involves more conceptual layers of a target system than debugging for time-sharing systems. Consider the case of debugging a C program within a time-sharing system. User-debugger interaction occurs almost entirely at a C language level of abstraction. Descent into assembly language and machine code representations of a target program is rare. Suspicions about a compiler bug may require inspection of generated assembly code.
Wireless
Wireless telecommunications, is the transfer of information between two or more points that are physically not connected. Distances can be short, as a few meters as in television remote control; or long ranging from thousands to millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of wireless technology include GPS units, garage door openers and or garage doors, wireless computer mice, keyboards and headsets, satellite television and cordless telephones.
Proposed system:
In the proposed system we make use of zigbee technology. It is used for the data transfer between electric meter and controller unit so we can avoid the physical burden of connecting physical wire. The loads are connected to the energy meter; meter reads the power of the load. Using IR Receiver, we sense the power meter reading when the LED blinks in it. The IR receiver output is given as an input to the microcontroller by means of analog voltage. This analog voltage is converted to digital through inbuilt ADC in the processor. These input details are transferred by using Zigbee technology through microcontroller. In the receiver side, the same details are again received by Zigbee modem and view the details in the PC by inbuilt UART communication in the microcontroller.
