Abstract

A smart deadlock system according to an embodiment of the present invention includes a thumb-turn, a key cylinder, a connecting shaft connecting the thumb-turn and the key cylinder, and a sensor module. The sensor module may include a sensing unit to sense a rotation state of a rotation sensing element inserted onto the connecting shaft, and generate sensing information associated with the rotation state of the rotation sensing element, and a rotation information generation unit to receive the sensing information from the sensing unit, and generate rotation information associated with an extent of rotation of the rotation sensing element based on the sensing information. According to the smart deadlock system, it is possible to check the operation of the deadlock more accurately by sensing the rotation state of the rotation sensing element using the sensor.
