Abstract

This project is to design and construct an energy meter. Normal energy meter show the amount of kilowatthour used but do not show estimated cost of electricty used. The meter just show you the kilowatthour that had been used for the whole month. This project is inspired by John Clarke, one of the magazine writers for 'Everyday Practical Electronic' .This project can help electrical appliance users to see the amount of kilowatthour that had been used. Every country has a different calculation of tariff for electricity, in Malaysia the first 200 kilowatthour is 0.218 cents, but after first 201 kilowatt the tariff is 0.289 cents. Even though cost appears cheap, at the end of the month, the amount of electricity used is high. This is because the electricity is used everyday, and sometime we do not realize the amount that we have actually used. As an electrical user, we have to use the electricity wisely to control electrical wastage even we can afford to pay. The energy meter is based on a special Active Energy Metering IC from Analog Device, ADE7756AN. PICI6F628A will derive the digital data and convert kilowatthour into Ringgit Malaysia and display it on LCD panel.
