The present invention relates to a digital door lock that is capable of detecting the rotations of a central gear and rotator in a non-contact sensing manner so as to accurately sense the locations where the central gear and rotator just rotate, and automatically sensing the opened/closed state of a door to check the operation state of the door lock itself by mounting a receiving sensor on a dead bolt assembly constituting an electromagnetic door lock device and a transmitting sensor on a strike box also constituting the electromagnetic door lock device, thereby lengthening a life span of the door lock.
