Abstract: A data logger device is provided. The data logger device according to an example embodiment of the present invention comprises: a sensing unit mounted on one surface of a flexible printed circuit board, and including a sensor that detects at least one piece of information; a display unit that, when an abnormal state is detected on the basis of information measured via the sensing unit, irreversibly displays the abnormal state; a control unit that controls driving of the sensing unit and the display unit; a power supply unit that provides driving power to the control unit; and a cover member that prevents the outside exposure of the sensing unit, the display unit, the control unit, and the power supply unit.

Abstract: An item location tracking device having anti-theft function is provided. An item location tracking device having anti-theft function according to one embodiment of the present invention comprises: a tracker body comprising a sensing part and a communication module for transmitting information acquired through the sensing part to the outside, the sensing part including a magnetic force detecting sensor for detecting a magnetic field, and at least one state detecting sensor for detecting state information of an item; a container-shaped bracket having an insertion space into which the tracker body is inserted, and fixedly installed to an item so that the tracker body can be fixed to the item; and a permanent magnet disposed in the insertion space so that a magnetic field for detecting whether the tracker body and the bracket are separated from each other can be provided toward the magnetic force detecting sensor.
