  2. Problem Statement • To create an automatic light switch • The device is intended to save power • Be able to integrate into a home automation system

  3. Potential Customers • Middle-class home owners • Owners of home automation systems • Modern home developers • Security system developers

  4. Design Aspects • Primary Detection will be done with a PIR sensor to monitor traffic movement in a room. • PIR sensor will operate by sensing the direction of the occupant to determine if the person is leaving or entering the room. • A counter will keep log of occupants in the room after initial activation of the PIR. • When counter is set back to zero and no occupants are present in the room, the lights will be deactivated.

  5. Secondary Control • Sound activation of the light will occur when an occupant will clap their hands. • The system will operate only after the PIR has detected an occupant inside a room. • Main purpose is to deactivate lights when going to sleep. • Will wok on a toggle feature based upon clapping sound.

  6. Third Control • Light sensitivity circuit will activate lights in daytime when gloomy weather or dusk is detected. • Main aspect is to allow occupants the security and safety of coming home to a lit home. Also creates an illusion of residency even when no occupants are in the room.

  7. Design Model

  8. Installation • The installation will be done by rewiring the manual light switch and connecting the automated light switch in coexistent. • The base unit will be placed near the manual switch. • Only template cover of the manual light switch will be replaced in order to accommodate the automated light switch. Nothing more is needed. • The automated switch will rely on a 9V battery for operation.

  9. Centralized System • Centralizing the base unit with a command unit for entire residence will be considered. • Application of fuzzy logic theory of simple pattern recognition of occupants will be researched. • System shall be targeted to become more involved in occupants daily routine to ensure less interaction with the system. • An example is when an occupant is cooking that the system will not shut off the lights when occupant goes to the pantry and would like to return after a few minutes.

  10. Production • PIR Sensor + Counter $60.00 • Light Sensitivity kit $12.00 • Sound activation kit $ 9.00 • ________________________________ • Approximate Cost $81.00 • $ 60.00-80.00 is required for an electrician to come to your home to replace a manual switch, on average visit; not including parts . Whereas, the light system we have designed will cost $81.00 but provide more functionality and elegance to any home.
