LUMEN ALARM & LIGHTING SYSTEM Artem 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)
