Autonomous LED system

1. what:

   • The system is develped for office useage, we try to provide "smart" function, making deskmans to have a better light working environment and with minimum distraction from it.

2. why:

   • Increase labour work effenciency
   • create a better working environment
   • Electricity reduction

3. how:

   • The system can automatically control the inner led brightness according to natural light it sensed, no human interference needed. But if the user want, of course, he/she can control the light by him/herself.
   • The system also provide auto switch-on/off based on the user attendance.

Main control work flow logic (pseudocode) and system introdction:

while Ture:
    if mode = auto:
        if USERPRESENCE:
            adjustLED based on natural light
        elif USERABSENCE:
            if absenceTime > 15 mins
                turnOffLED()
            if absenceTime < 15 mins
                pass
    elif mode = manual:
        adjustLED based on user selection

As a distrubuted light control system

• Configuration:

• PIR motion sensor:

• Light sensor:

• Button:

• Led:
