Risks and Contingencies



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: ATMega8

RF link: ZigBee Wireless

Magnetic sensors: HALL effect switch

Glass Integrity: Glass Break Detector

Temperature: Analog or Serial

Infrared 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 poweredby AC

All digital components and chips willrun at 3.3V



Extras

Control the coffee pot or oven

Lock doors

Camera nodes

Real time graphs of each sensor

Other Control Nodes (Turn on lights,open garage door)

SMS notification



Division of Labor

Risks/Contingencies

1. Wireless communication adds tosensor interface complexity*Remove wireless link from sensors.Use simple wires.

2. Number of remote units increasescomplexity

*Decrease number of remote units



3. PC interface functionality of graphingand displaying data*Simplify the Visual Station graphingfunctionality

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

Visual Station instead
