Design of wireless smart metering system based on MSP430 MCU and ZigBee for residential application

Wireless smart metering is an integral part of smart grid to realize kilowatt-hour metering, real-time data acquisition, meter reading analysis, real time monitoring and decision making etc. In this paper a low-power wireless communication system based on 16 bit MSP430FE4272 MCU and ZigBee is designed. The system architecture and the design of hardware and software are introduced in details. The designed system realizes the functions of realtime data acquisition, wireless transmission and communication between the smart meter and the central computer with the help of standard ZigBee modules.
