What is ZigBee
Protocol developed by the ZigBee Alliance and their
members
Designed for lost cost, low power wireless networks
ZigBee protocol features include:
• 802.15.4
• 250 kbps data rate
• Low duty cycle
• Low latency
• 128-bit AES encryption for secure data connections

ZigBee Continued
Other Features:
• Support for multiple network topologies
• point-to-point
• point-to-multipoint
• mesh networks
• Collision avoidance, retries and acknowledgements
• Supports up to 65,000 nodes

Proposed Room Architecture
Purpose
• Reduce power consumption in homes
• Found that 10% of household power is used by appliances
while in standby mode
• Use a Zigbee MCU control structure
• Aids in home automation
• Control many different home appliances
• Customized remote control options

Standby Cut-Off Power Outlet
• Monitor power consumption through outlet
• Reconfigurable firmware for different appliances
• Relay is controlled by the MCU

Boot:
• Executes firmware
• Modified for different appliances
On:
• No power monitoring
• Turns on relay
• Allows the power to flow
Normal:
• Monitors the power consumption
• averaged
• Turn off relay
Off:
• Wait for turn-on command through ZigBee

ZigBee Controller with IR Learning Functionality
IR Learning:
• Push and hold button
• sdfgsdhfg
• Press twice
• to configure button to an IR code
• IR used as recognition to send signals over ZigBee

ZigBee Controller
Point remote at IR receive:
• Configure buttons
• Different buttons – different commands
• Control Lights
• Can be attached to the wall
• Buttons used to wake up outlets

Results
Tested design on a 37 in flat panel TV:
• Standby power is 550mW
• Set on firmware to 800mW
• After 2 minutes, outlet shuts off automatically
• Programmed buttons on a TV remote
• Power button
• At TV – turns on TV
• At ZigBee Controller – turns on outlet
Normal outlet standby = 1W
This board = 140mW

Conclusion
Successful implementation
• Reduced wasted standby power
• Remote controllable
Future:
• Link together through a home server via zigbee
• All home functions from one area/remote
• Home Automation
Possible surge protector configuration?
