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

Our Product

Manual, automatic control of lights Automatically control lights according to room

occupancy, programmed alarms Energy efficient Cost: $300 for control panel, $213 for light bulb

Design

Two components Control panel module

Backlit LCD, pushbuttons, speaker, occupancy sensor

Alarm clock functionality Standard electrical outlet

Light modules Standard light sockets

Wireless communication

Problems

LED power supply is too long Solution: Cut it in half

UART not working correctly between PIC microcontroller and ZigBee antenna Solution: Set PIC’s low voltage

programming OFF

LEDs overheat Solution: Use better heat sink or run LEDs

at < 200mA

Technical Specifications

Control Panel Unit: Functions as Alarm Clock Consumes low power (< 5W)

Light Bulb Unit: Uses at least four high power LEDS Reduces power consumption through switching

power supplies (<15W) Dims LEDs through PWM (0 to 1.5W)
