Overview

Project Objectives and Purpose Approach Sub-systems Division of Labor Schedule Risks and Contingencies

Project Statement

Home Security and Safety Detection of intruders Intruder prevention by alarms and lights Recording of home activity Generate reports (logs) Allow remote access

Motivation for Implementing

Allow home owners to always know what is happening in their house Allow remote access to the system Fend off intruders

System Diagram

Control System

Communicates with each sensor Communicates with Visual Station Records data from sensors Responds to events (trigger alarm)

Control System

Main control processor: ATMega128 RF link: ZigBee Wireless Internet: TBD Ethernet module Data Storage: SD cards Alarm Trigger: Standard IO Programming: C/C++ using Eclipse Visual Station: Connected via Serial

Sensors

Infrared motion detection Magnetic proximity for doors/windows Glass integrity sensor Temperature sensor

Sensors

Simple control processor: ATMega8RF link: ZigBee WirelessMagnetic sensors: HALL effect switchGlass Integrity: Glass Break DetectorTemperature: Analog or SerialInfrared Sensor: Self-Designed

Visual Station

Contained within a laptop Continuously updating sensor values Graphically displays information Monitor and control system settings

Alarms

Lights Noise (siren) Email

Power Sources

All parts of the system will be powered by AC All digital components and chips will run at 3.3V

Extras

Control the coffee pot or ovenLock doorsCamera nodesReal time graphs of each sensorOther Control Nodes (Turn on lights, open garage door)SMS notification

Risks/Contingencies1. Wireless communication adds to

sensor interface complexity*Remove wireless link from sensors. Use simple wires.

2. Number of remote units increases complexity*Decrease number of remote units

3. PC interface functionality of graphing and displaying data*Simplify the Visual Station graphing functionality

4. Remote access via web server*Simplify the web server or use the Visual Station instead
