Refrigerator Timer

A timer for turning ON/OFF the refridgerator at peak load hours (6pm to 10 pm) using 8051

    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).

    Features:
    • 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.
