What is it?

A low-cost power-money meter.

Why did you make it?

To raise awareness about energy consumption and deepen a new habit of unplugging when not necessary to save energy toward a greener and sustainable planet.

What makes it special?

The pocket size, components and precision.

As far as for today the power-money meters aka FENOMENO is a 9x9x3 cm3 device that can display real time energy consumptions in any residential household or commercial installments under a breaking agreement of 16100mA. It then helps in raising and/or building awareness about energetic challenge human face by showing how much of a waste unplugging could save, how voracious an old device is knocking down our electricity budget and so on and so forth... Mainly it can forecast AC voltage, power, accumulated energy and clearly Money be it in any currency needed from the end-customer.

The circuit is largely based on Stc8h1k28 accompanied with zmpt112 current voltage sensor, a current sensing module, some 21 smd resistors, 16 capacitors and a diode and a COG 16 characters display module...
