4th Annual Senior Design SymposiumOn Renewable & Sustainable Energy

Friday, April 13, 2012Department of electrical engineering and computer science

Smart Home MotivationEnergy costs continue to riseEnergy independence is an

important national issue, with energy conservation as a key component

With the advances in mobile technologies, people want increasingly more access and control over all aspects of their lives

Speaker: Dan Arnett

Similar TechnologiesThere are already companies in industry that

have similar implementations such as Project Jarvis and Home Automation, Inc.

For our Senior Design project, we wanted to create a Smart Home that helped conserve energy, allowed for remote access over the internet, and allowed us to showcase our electrical and computer engineering skill sets.

Energy Consumption In 2001, families with gross annual incomes below $50,000 spent an average of

12% of their average after-tax income on residential and transportation energy. By 2005, energy costs rose to 16% of their average after-tax income. In 2012, these households are projected to spend 21% of their average after-tax

income on energy. (DOE/EIA Short-Term Energy Outlook released in January 2012) The categories of home energy usage that this project aims to decrease are:

Home Electronics 7.2% Lighting 8.8%

Smart Home – Energy SavingsThe first component of the project reduces

energy consumption by shutting off unused lights by automatically sensing when someone leaves a room.

The problem with a setup that uses continuous sensor inputs alone is that once the sensors do not sense any activity, the lights will shut off in that room.

This is a problem if someone is in a room, but not moving, and the lights go out since no activity was sensed after a period of time.

Speaker: Dan Arnett

Smart Home – Energy SavingsThis project gets around this problem by placing motion

sensors in each room and at each doorway. If someone walks through a doorway, the sensors in each

room will look for motion, thereby detecting if someone has left the room, or entered the room.

This will prevent the lights from turning off unless someone has left the room. This setup will conveniently allow someone to go from one room to another without having to turn lights off and on as they leave and enter rooms.

That convenience will be combined with the energy savings of eliminating instances where someone forgets to turn off lights in unoccupied rooms.

Speaker: Dan Arnett

Smart Home – Remote AccessThe second main component of the project is

a website that is hosted on the main microcontroller that will allow a user to remotely access their devices connected to the network from any web browser.

There will be a graphical user interface on the website which will allow the user to view the status of and turn on and off lights and electronics in various rooms.

Speaker: Joseph Vanciel

Smart Home – Key ComponentsTI MSP430 – Microcontroller, used in our

system to both configure our devices and processor input from the motion sensors

TI Stellaris – Microcontroller, used in our system to host our website and communicate all information from the MSP430 to the website.

NaPiOn Passive Infrared Sensor – Motion sensor used for detecting motion within each room and at each doorway

Smart Home - Prototype Design For demonstration purposes, a model house was

constructed out of wood, having three mini adjoining rooms and three doorways:

Graphical User Interface (GUI)Once the user pulls up the IP address of the

Server in their browser, the GUI will appear in the user’s web browser.

The GUI will display the status of the lights and electronics

in each roomallow the user to turn a light or electronic

device on or off by clicking the appropriate button

Smart Home Demo

SummaryIn conclusion, we took on this project

because it interested us and it was a project where we knew we could put our theory learned in school into practice

We got the opportunity to learn all the business aspects of what goes into an engineering design and implementation

We also learned how to work with, write software for, and trouble shoot several different microcontrollers
