NafarYab / elevator


Many times when people push up / down button for using elevator cabin, they may need to wait so long because of people using the cabin in other floors. As a result some of them prefer other cabins or many choose staircase, however, the cabin is programmed to arrive chosen floor even if there are no longer any people there.
Nafaryab uses an ultrasonic sensor which is mounted on top of elevator door frame, detects the person who pushes the up/ down button, then cabin moves to the chosen floor only if he stays in the detection zone which is shown by yellow line, thus this system decreases waiting time,electricity waste and sublation of parts.
