Smart LED

An AVR board to control home lighting autonomously. It provides automatic control of LED lighting (12vdc) according to:

  • Time schedule: active during daily work time except for holidays.
  • People movement: turning on lighting automatically when sensing movement using a PIR extension.
  • Electric supply status: provides auxiliary lighting when needed (in case of a power outage).
  • Illumination level sensing: no need to turn on the lighting when there is enough lighting.

Also providing manual control:

  • Directly using onboard buttons.
  • Remotely using an infrared remote control (RC5 based).
