Air quality measuring device with access point capability

摘要

An air quality measuring device having an access point function is provided. The air quality measuring device includes: an access point module that receives an Ethernet communication signal by wire, transmits a wireless Internet signal, and communicates with a wireless and wired device according to an Internet protocol; one or more sensor units for obtaining measurement information by measuring a predetermined measurement target for indoor air quality; a Power over Ethernet (PoE) unit for extracting and providing power required for the operation of the air quality measurement device from the communication line introduced into the access point; and a central control unit for controlling components of the air quality measuring device according to a command received from an input device through the access point module, and receiving the measurement information from the one or more sensor units to determine air quality. According to the present invention, the power supply is made directly from the Ethernet signal, and the measured information is transmitted and received through the access point module, so that the installation of the air quality measuring device becomes easy, and in case of a dangerous situation, an acoustic signal through a speaker and a laser projector Since it simultaneously outputs visual signals through the
