Status Report # 3Commhut – Home Security Wire

Protection System

Team 7Ronald, Orlando, Robert, Jaime

An interfacing module to communicate with previously designed protective

case.

OVERALL NEED: To protect the communication lines of home security systems by detecting intrusion.

DESIGN MILESTONES:◦ Develop Detailed Schematics for interface (On going)◦ Receive sample code and sample products from Mr. Poston

(Mid February)◦ Interface modem with the PIC Microcontroller (2/20/09)◦ Continue constructing source code for PIC (2/20/09)
