Project Overview

• Initial design called for a pre-designed
  wattmeter.
• Redesigned using TIs MSP430F2013
• Hardware Design
• Wattmeter
• Power Supply
• Board Layout
• Software Design
• MSP430F2013 (C)
• MICAz (nesC/TinyOS)
• User Interface (Java)
• Communication Layers
• MSP430F2013 -gt MICAz
• MICAz wireless network to base station
• Base station via UART to host PC

Project Conclusions/Outcomes

• Implemented a wattmeter and a wireless network
• Implemented a user interface
• Successfully designed and implemented a PCB
• Could not rectify communications between
  wattmeter and wireless section
• Overall result useful learning experience, but
  did not meet specifications
