A door knob that controls the electricity

Quite often we go home and discover that they had left on the lights or forgot to turn off a device. This in time is felt on the electricity bill. A group of designers has found a potentially effective way to avoid this. This is a door handle like no other. Indeed, the handle is to be a device to control electricity and even gas.

 

Upon leaving, the owner of the house or apartment is able to extinguish all light and electrical appliances from the handle thanks to orders placed on it.

The device can control only the lights, gas, or all at once. Jinhyuk Rho, Rho and Kim Maria Eunah devised the concept.
