    the board what iam thinking to use is in above fig plz suggest whether it fits my requirement

    the properties of board are

     

    • The board is built on a high quality FR-4(1.6 mm) PCB with a green solder mask and a clear and legible white legend. All IO pins are labelled with their names along with any dual feature they support. This greatly simplifies prototyping.
    • Onboard USB to Serial converter for serial communication and programming over USB
    • Onboard 16×2 LCD support
    • Onboard RS232 interface circuit for easy communication with a computer and other serial devices (GPS modules, GSM Modems, etc)
    • DC plug-in jack for power input
    • Onboard bridge rectifier enables the board to accept both AC and DC input voltages
    • Onboard 5V regulator(LM7805) with filtering capacitors and heatsink
    • Power Status LED(Green) and 4 x general purpose user LED(Red) and Switches
    • Onboard quartz crystal 11.0592 Mhz oscillator circuit
    • Port extensions for all ports with detailed pin labeling for easy identification of pins
    • External pull-up resistors for Port 0
    • Vin, 5V and Gnd bus provided for easy and simple expansion
    • The package includes a CD and product manual

    The project is possible. Thanks for sharing this much information. But I wonder why you haven’t post the name or part numebr of the board. That’s what we expect.

    Also share us how do you calculate the enery consumed?

    Hi,

     

    Its very easy one.

     

    You need following things.

    1. Current Sensor

    2. Controller 

    3. ADC (controller with ADC like ARM7 will be useful)

    4. Transformers

    5. ZERO CROSSING DETECTORS
