Refrigerator Timer 2013-09-29

As you know the refrigerators are notorious for its energy consumption. At the peak load hours that is from 6pm to 10 pm, there will be a drop in voltage and high current drawing equipments will draw more current at that time.

Here I present a crude 8051 based circuit for overcoming that. Its very low cost and durable (I tested it my self).

  • Automatic cutoff from 6pm to 10pm
  • No RTC, time is kept by running on rechargeable cells.
  • Dirt cheap (I mean it :D)
  • Doubles as a kitchen clock.
