Mounted, the air flowed through the air sensor 15 in the housing 11 through the air sucked into the one side vent 13 can be formed.

On the other hand, the control unit 16 embedded in the sensing device 10 is configured with a network adapter transmitting unit 17, connected to the wireless network 40 as described above, and eventually establishes a communication path with the management server 50 to be described later. It is occupied and utilized, where the wireless network 40 performs TCP/IP (Transport Control Protocol/Internet Protocol)-based communication with traditional mobile communication networks such as Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA) methods. Wireless LANs and mobile communication networks constituting the wireless network 40, although not shown, include wireless LANs such as Wi-Fi (Wireless-Fidelity) and WiBro (Wireless Broadband), and Long Term Evolution (LTE). Each is connected to the management server 50 through a gateway server and a communication provider server, which may be a kind of gateway server.
