The present invention relates to an IoT (Internet of Things) device, a mobile terminal, a method of pairing the IoT device using the mobile terminal, and a control method. According to one embodiment of the present invention, the method includes the steps of, when an IoT device contacted with at least one side of the mobile terminal is recognized, generating a vibration using a designated vibration pattern, receiving vibration pattern information from the IoT device, and when the received vibration pattern information is identical to the designated vibration pattern, performing paring with the IoT device. According to the embodiments of the present invention, a user can intuitively perform pairing between the mobile terminal and the IoT device through the paring method between the mobile terminal and the IoT device.
