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:

UART not working correctly between PIC
microcontroller and ZigBee antenna
 Solution:

Cut it in half
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)
