  1. Active daylight systemPresentation #26 2/8/10

  2. Background Light Bulbs are Being Used in Homes During Daylight Hours While Sunlight is “Wasted” On the Floor An Economical, User Friendly Way to Use This Sunlight is Needed

  3. possible solutions Redirect Sunlight To Desired Location Using Solar-Tracking Mirrors - Only Get What Comes Through Windows “Pipe” Light Using Fiber-Optics - Expensive, Not User Friendly

  4. My solution choice Multiple Mirrors Oriented Similar to Venetian Blinds

  5. System Diagram

  6. Mechanical Components -Mirrors -Bearings -Frame -Shafts

  7. Main Mechanical Components

  8. Critical Details

  9. Software Components • Hardware: • HCS08 Microcontroller • -Elmo’s E910.86 Sun Angle Sensor • -Servo Motors (Detailed Under Electrical)

  10. Software Overview

  11. Elmo’s E910.86 Sun Angle Sensor -Very Small, Blocks Little Light -Outputs a PWM signal to HCS08 with Sun X and Y Angle Data -Outputs Temperature -Generally Used for Automotive Industry for Auto-Tinting Windows and Climate Control

  12. Electrical Components -12V Power Supply - 5V Regulator to Power Servo Motors - Schematic Coming Soon

  13. Servo Motor • HiTec 1/4 scale and 1/8 scale • HCS08 inputs a PWM, pulse width determines angle. • Acts as a smart device in this system

  14. Management • -Only Group Member. • -Spoke with Sales Representatives to Request “Samples” or Donations. • -Working in Conjunction with Other Groups to Share Responsibilities.

  15. Budget

  16. How Long will it take?

  17. Coming Soon • Study of money saved through this system. Light bulb power/lux vs. Mirrors power/lux • Schematic

  18. Questions?
