摘要： A method of connecting an access point (AP) device is provided. The method includes receiving media access control (MAC) address information of a terminal from the terminal through an external device, registering the received MAC address information, and determining whether the registered MAC address information corresponding to MAC address information registered to another AP device. In response to the registered MAC address information corresponding to the MAC address information registered to the other AP device, an AP device managing the registered MAC address information is determined among the AP device and the other AP device. A connection request is received from the terminal, and the terminal is connected to the AP device based on whether MAC address information of the connection request is corresponding to the registered MAC address information.

摘要： Disclosed is an optical gas sensor. The optical gas sensor includes: a light source which emits light; a gas collector which includes a cavity to be filled with gas to be sensed; an optical wave guider which guides light emitted from the light source to be output to the cavity, and guides the output light to be output again to the cavity after passing through the cavity of the gas collector; and an optical detector which detects light output from the optical wave guider. Thus, a path of light exposed to the gas to be sensed is increased within the cavity, thereby achieving miniaturization and sensing gas of low-concentration.
