I was walking through the hardware store the other day and I walked past an energy meter which clips onto your homes electricity mains and then provides you. I recently installed a new motherboard into my computer ASRock z77 Extreme4 and am receiving messages that say to install the driver for Universal Serial Bus USB. Simple Arduino Home Energy Meter 5 Steps with PicturesAs mentioned above, because your setup, CT, resistors and input voltage may be different, there is a scaling factor in the sketch which you will need to change before you will get accurate results. To calibrate your energy meter, your need to be sure that the current that your meter says is being drawn is what you expect is actually being drawn. In order to do this accurately, you need to find a calibrated load. These are not easy to come by in a normal household so you will need to find something which uses an established and consistent amount of power. I used a couple of incandescent light bulbs and spot lights, these come in a range of sizes and their consumption is fairly close to what is stated on the label, ie a 1. W light bulb uses very close to 1. W of real power as it is almost entirely a purely resistive load.

You will now need to adjust the scaling factor uses in the calculation line double RMSCurrent max. Current 5. 160. In this case it was 1. Either use linear scaling to calculate this figure or, if youre not good with math, play around with different values until the load you have plugged in is shown on the energy meters screen.

The first number displayed is the instantaneous current followed by the instantaneous power. On the bottom line, the kilowatt hours used since reset and then the maximum recorded power since reset.
