It is undoubtedly that in the future, energy would cost more as the direct result of steady increases in power generation cost and since the energy consumption may exceed its productions. The idea of designing the Digital Household Energy Meter is due to the basis that it would indirectly helps to create a better understanding and awareness towards the value and the importance of electrical energy, energy saving, promoting of smart energy management as well as an innovation towards further improvement to proven existing system. It was also due to the fact that in times to come, the cost of electrical energy generation continuously increase and the energy consumption may exceed its productions or generations. By realizing such idea, end users are provided with the proposed system to assist them in carefully planning and managing their electrical consumption. Thus, power wastage could also be reduced to the minimum level and helps to ease the arising problems. The prototype is integrated with an interval meter, Mk 6 Genius electric meter that is capable of register the energy consumption in a specified period of time through an optical serial communication probe that is IEC1107 FLAGTM compatible to a central computer for processing. The serial port analog to digital converter was used in the communication system and attached to the computer through RS-232 interface. The computer will then display the electrical consumption pricing in a display panel. Microsoft Visual C++. 3ET is used as the development platform specifically for the data processing and user interface design. The prototype was meant to compensate the current system and able to provide accurate, reliable and instantaneous meter reading and displays the users’ electrical consumption in terms of price unit
