Wireless Sensor Network Application: Smart Meter Using Smart Card

Smart grid, as an intelligent power generation, distribution, and control system, needs various communication systems to meet its requirements. Automatic meter reading and more precise prognoses come within technical reach due to wireless sensor networks for smart metering and the smart grid. The radio nodes exchange data wirelessly in bidirectional communication and forward them to the master node. In the smart meter module consists of a micro controller (At mega 16) interfaced with passive rfid module and is interfaced with zigbee module and is connected to the master module with 802.11 ethernet interface.Using smart technology ;smart meters are interfaced with passive rfid and zigbee and smart meter will behave like a post paid mobile phone where passive rfid is used to pay electricity bills and recharge. This paper describes about how a smart meters work and how smart meter is helpful in paying bills wirelessly and need for a person collecting bill is removed.
