Everyday important items are lost or stolen!

Wireless Monitoring to the Rescue

Objectives Base Station Sound and Vibration Alerts Wireless: Zigbee Possible Expansion: RFID, Bluetooth Wireless Mobile Unit Power management Minimize size and Maximize Battery Life User Interface USB connection with computer LCD Display

Possible Expansions Integration of multiple wireless standards for short, medium, and long range device monitoring and protection. Standalone base station where modules could be synced with base station without the need of a computer Modules minimized in size and power draw Additional features for modules Sound and vibration alerts

Sub System Implementation

RF XBee 1mW Chip Antenna Broad Support with the Arduino Low-cost, Low-power Short-to-mid range Has range control

Microcontroller Platform Arduino Duemilanove Minimal processing demands, handshake with modules, poll device status Low Power, Low Cost Open Source Scalable Strong Documentation

Microcontroller ATMega328P 8 Bit Microcontroller 32K of programming space 23 I/O Lines Up to 20 MHz with external Crystal 1.8 V - 5 V Operating Voltage

Smaller ATMEGA for Mobile Modules ATMega328 8 Bit Microcontroller 32K of programming space 23 I/O Lines Up to 20 MHz with external Crystal 1.8 V - 5 V Operating Voltage

What we have done so far

Power Base Station: USB powered If possible make it portable with battery power Modules: Battery Power Want to minimize power consumption Small Battery controller and regulator

Human Interface LCD screen to give the user feedback on system status and operation Have a donated LCD display might be used USB interface with computer Possible expansion : addition of modules without the need of a computer Alerts with sound and vibration

Sustainability Parts could be made from multiple manufacturers. Open source micro-controller platform that is available from multiple companies. Limited number of moving parts, modules could be bought separately if individually lost. Wireless standards will be used for communication.

Safety and Regulations All communication protocols will fall within the requirements of the FCC standards. All voltages of the system will be < 15 V Users will not interact with any power systems greater than the power that comes from a wall socket.

Risk and Contingency Small Team Scalable project that can adapt in feasibility RF Communication and Identification Issues Use of wireless standards, software solutions to identify our modules from general RF noise Unexpected hardware/software problems Online documentation, built in overhead for hardware failure, Instructors and TA’s

Updated Schedule

Milestones CDR Communication between modules and base station. Base station and modules can recognize each other. Completed on 10/1/2010. Six days before CDR Milestone One Full software implementation and alerts working when modules leave network Milestone Two Full user control with feedback, product is in final packaged state with printed circuit boards and full software
