  2. Outline • Project overview • Block diagram • Design challenges • Individual contributions • Project demonstration • Questions / discussion

  3. Project Overview • Digijock Home Security (DHS) is a wireless alarm system designed to protect homes from fire and burglary. • Target: • Inexpensive, full-featured system • Features: • motion, noise, smoke and temperature sensors • Web enabled/controlled

  4. Block Diagram Remote Sensor Unit Central Monitoring Station

  5. Design Challenges • Component selection - RSU • PCB design • XBee Wireless module • Voltage translator • network configuration • Interfacing LCD with Atom board

  6. Individual Contributions • Team Leader – Linda Stefanutti • Team Member 2 – Stuart Pulliam • Team Member 3 – Will Granger • Team Member 4 – Zach Smith

  7. Team Leader – Linda Stefanutti • Organization of the team work • Initial design • objectives, research, selection • Circuit prototyping • Remote Sensor Unit software • Packaging • Final prototyping

  8. Member 2 – Stuart Pulliam • Selected and purchased components • Designed and prototyped sensor circuits • Designed PCB • Debugged wireless, etc. • Final packaging design • Wrote CMS LCD program

  9. Member 3 – Will Granger • Came up with team name • RSU software • Preliminary PCB • Packaging • Update website

  10. Member 4 – Zach Smith • XBee Wireless Network • Web Application: .NET and ASPX • CMS Main Program: C# • Database: SQLServer 2005 • Soldering PCB • Packaging

  11. Project Demonstration • An ability to detect motion based on temperature variance, noise above 90dB, the presence of smoke/combustion with a photoelectric amplifier, and to measure temperature with a thermocouple amplifier. • An ability to encode and transmit data packets wirelessly to/from the remote sensors with a sensor identification address included in each packet. • An ability to arm/disarm the security system and to alert the user (visually, audibly, and through email) of emergency conditions from both the CMS and the remote sensor units. • An ability to time stamp events and log them in non-volatile memory on the CMS. • An ability to display event logs and operational status on an LCD as well as a webpage hosted by an embedded web server. Demo

  12. Questions / Discussion
