Abstract
The group will focus on the design of a “smart” device. This includes
researching the best method of design and fabricating the design to
create a working device. The team considers a smart device as any
piece of electronic equipment that is highly automated, or imitates
human intelligence (ex. smart missiles). The smart device that the
team chose to implement is a home automation system using the X-10
protocol. The team hopes to finish the year with a fully functional
home automation system.
End Product Description
The X-10 Home Automation System will simplify several tasks for a
home owner.
With home access via the web, maintaining and
securing one's home can be easily done from anywhere an internet
connection is available.
X-10 allows a user to turn off lights,
close/open garage doors, and even change the temperature of their
home.
Introduction
GENERAL BACKGROUND
• Design, implement, test and demonstrate one or more smart
devices chosen by the group
• Chosen device is a home automation system using X-10 technology
• System includes a host computer to act as a secure web server and
X-10 device controller
• Appliances connected to the X-10 network will be monitored and
controlled via the host PC, website, and/or a web-capable cell phone
Technical Approach
• Design the web page for the home automation system controls
• Setup the home network using X-10 protocol
• Configure X-10 controllers and sensors
What is X-10?
X-10 is a communications
"language" that allows
compatible products to talk
to each other via the
existing 110V electrical
wiring in the home.
Controlling Web Site
TECHNICAL PROBLEM
• Connect several devices, lights, and appliances to X-10 receivers
and monitor and control them via a PC in the home
• Extend this control to the internet via a secure web site which
allows the homeowner to monitor and control the devices remotely
Home
Computer
OPERATING ENVIRONMENT
• Residential setting
• Indoors and/or outdoors
• Limited security (neighboring homes on the same electrical
transformer may experience interference in their X-10 network)
Cell Phone
Remote
Computer
X-10 Controller
Supports up to 256
devices
INTENDED USERS
• Anyone who wants to be able to control their home from any
computer connected to the internet
• Anyone who wants extra security associated with home monitoring
Key

Internet
Power Lines
Directly connected
INTENDED USES
• To make the users life simpler by automating everyday occurrences
such as turning lights on and off
• Create and run macros to control several X10 devices at once
• Allow remote monitoring and control via the internet
NOTE: Arrows indicate direction of data flow
Lights
Testing Approach
• Testing the home automation system requires the use of the
internet, the X-10 controllers/receivers, and devices to control or
monitor
• Before full system testing, the new software and new hardware will
be tested individually to ensure their functionality
• Passing the system test includes full operation of all X-10 devices
and the software shall allow the ability to quickly add new devices
Budget and Personnel Effort
LIMITATIONS
• No outside funding for this project
• Project shall be completed in two semesters

FUNCTIONAL REQUIREMENTS
• Sensor and control devices shall use X-10 protocol
• Software shall be configurable to add new devices
• Control and monitoring webpage shall be viewable from any web
browser
Locks
X-10 Home Automation System
ASSUMPTIONS
• Devices shall have a manual override to ensure their functionality
when the X-10 network is not working correctly
• User shall be familiar with operating a computer
• House shall be X-10 compatible (low levels of interference on 110V
wiring)
• System shall function without the presence of the website for those
choosing not to utilize that ability
DESIGN OBJECTIVES
• Create software to provide web based home automation
• Develop additional sensors and controls to monitor and control
new devices on an X-10 network
