PowerSocket – On-Outlet Power Consumption Visualization


How much power does your hairdryer consume? What about your coffee machine? This is something that you could easily measure with a personal energy meter (PEM), but do you own one? And have you measured the consumption of all devices in you household?
What if we could easily see the current power consumption directly at the outlet? PowerSocket does exactly that! A lit-up ring around the outlet rotates and fades from green to red with increasing power consumption.
