System Overview
Base Station Software Overview

• Design The Energy Smart Room is meant for simple
  set up in any room featuring one entry way. This
  means offices, conference rooms, studio
  apartments, bedrooms, etc. The Energy Smart Room
  is designed to interface with several common
  heating, cooling, and lighting appliances. It
  can be used with just heating, just cooling, just
  lighting, or any combination of the three,
  depending on what best suits the environment and
  needs of the user. Appliances it is designed to
  interface with include lamps, overhead lights
  with traditional wall light switches, window
  blinds, space heaters, and window air
  conditioning units. Other integrated heating or
  lighting units will need to have special
  solutions designed for them, and may not be
  compatible with the Energy Smart Room setup.
  However, if a room for example has integrated
  heating or cooling solutions already, the system
  could still be used just for lighting.
• Devices The Energy Smart Room features several
  devices that make it work.
• A user recognition system will be installed by
  the doorway to the room. This will sense when a
  user enters or exits the room. It will also
  incorporate an RFID unit that will sense if a
  user is carrying an RFID card, and if so, use
  their own personal heating and lighting
  preferences rather than default settings. This
  is powered through a traditional wall outlet.
• Two to three sensors will be placed across the
  room. These units are small and battery powered.
  They will monitor the heating and lighting
  conditions in the room and wirelessly send this
  data.
• A base station unit will be used to control the
  overall system. This will be the main processing
  component of the system, and where users set
  their desired temperature and lighting settings.
  It also can be used to set which users have
  priority. In addition, the system will keep
  track of time, so that heating or lighting
  conditions can be turned down when a user is
  sleeping or at work.
• Finally, output devices will be incorporated
  into the output devices previously specified in
  order to control the temperature and lighting.
  They will also relay power consumption data back
  to the base station for supported output devices,
  so that when possible, the base station can
  determine the most energy efficient way to reach
  the desired settings.

The base station is an HC11 microcontroller
programmed to do most of the processing within
the system. It is connected to a mote, the
doorway entry sensors, and controls the power
supplied to the RFID reader. The program
controls the operation of almost the entire
system by sending commands to the motes
indicating whether outputs should be turned on or
off. In addition, it takes user commands in
directly through a keypad and displays the
current settings and conditions on an LED
display. A basic block diagram of the operation
of the code is shown below
ABSTRACT
This project focuses on reducing energy
consumption and increasing personal comfort by
monitoring the conditions present in a room and
adjusting the rooms environment to meet peoples
desires. The goal of the project is to create a
system to implement in a room, which can sense
the presence of a specific person or a general
person, and adjust lighting and temperature to
fit the needs of those people. This project
was done using radio frequency identification to
determine specific people and adjust the room to
their specific conditions. There are also motion
sensors to detect people who enter the room but
do not have a radio frequency identification tag.
In this project wireless sensor networks, or
motes, are used to determine the current
conditions of the room, and report these
conditions to a base station. The base station
analyzes the information from the motes, and
sends out signals to various operators in the
room, to change the room conditions. The
operators control the lights, blinds, and heating
or cooling devices. The main objectives of this
project are to conserve energy and make the
system affordable and easy to install for the
average person.

The HC11 microcontroller This is the base
station of the system, and provides the main
processing power. It is connected to the motes,
the power supply for the RFID reader, and the
doorway entry sensors

MICAZ mote board This is one of the main
communication boards in the mote system. It can
connect to sensor boards or output boards. On
the output boards, signals can be connected to
relays or other circuits to turn outputs on or
off, or adjust their settings
ADVISOR
Dr. Insup Lee - CIS
Mote Sensor Board These take in the temperature
and light readings from the room and communicate
them to a MICAZ communication board. These
signals are then sent on through the mote network
to the base station.

DEMO DATE
RFID Reader This senses RFID tags on any users
entering or exiting the room. If these users are
carrying an RFID tag, they will be identified by
the reader. Their identity will be sent to the
base station so their person settings can be
applied
