LUMEN ALARM & LIGHTING SYSTEM Artem Aginskiy, Grayson Carr, Yinuo James Chen, Andrew McDowell

Our Product  Wireless control of room lighting  Automatic control of lights according to room occupancy, programmed alarms  Manual dimming  Energy efficient  Cost: $300 for control panel, $213 for light bulbs

Design  Two components  Control panel unit Backlit LCD, pushbuttons, buzzer, motion detector Alarm clock functionality Standard electrical outlet  Light bulb units High power LEDs Standard light sockets

Status  Completed:  Wireless testing  LED Connections  Control panel hardware  Control panel menus  In Progress:  Integration and debugging

Previous Problems  LED power supply too long  Solution: Cut in half  LEDs overheat  Solution: Bought heat sinks, built a spotlight array

Recent Problems  Real Time Clock not running:  Solution: Created new control panel  Pushbuttons not cycling through menu:  Solution: Grounded, fixed coding error  Debugging taking long time:  Solution: Modularized code

Control Panel Unit  Alarm clock functionality  User-configurable settings  Clock with coin cell backup  LCD user interface  Serial connection to computer for debugging

Control Panel Menus

Light Bulb Unit  Uses six high power LEDS  Interacts wirelessly with control unit  Flashes upon alarm  Plugs into standard light bulb socket  Dims LEDs through PWM (0 to 1.5W)

Light Bulb Test Unit  Serial connection to computer  LCD debugging output  Plugs into standard light bulb socket  Power:  Watts at 0.12 Amps  Watts at.98 Amps

Future Work  Multicolored LED light bulbs  Allow user adjustable colors  Powerline communication instead of wireless  Eliminates wireless interference  Improves indoor range  Photocell for ambient light sensing  Provide automated light dimming
