As an example, the item selection button may include, but is not limited to, an ultra-fine dust button, a fine dust button, a temperature button, a humidity button, a formaldehyde button, and a carbon dioxide button, and a weather button for outputting weather information is enlarged. It may include, but is not limited to, an advertisement button for outputting, a news button for outputting main news information, a traffic button for displaying surrounding traffic information, a public transportation button for displaying public transportation information, and the like.

The example of FIG. 10 shows an output screen when the fine dust button is selected.

A real-time comparison result of indoor air quality and outdoor air quality may be output in the selection item display area 1010 .

In the message display area 1020 , a guide message based on a comparison result of indoor air quality and outdoor air quality for the selected item may be output. For example, when the indoor air quality is better than the outdoor air quality, a guide message such as "The indoor air quality is better than the outdoor air quality. It would be good to stay indoors today" may be output.

In the other item information display area 1040, air quality information corresponding to an air quality item not selected by the user may be displayed.

The advertisement display area 1050 may display advertisement information.

The advertisement information and the outdoor air quality information may be obtained from the remote management server 130 , and the indoor air quality information may be obtained based on sensing information collected by the sensor board 110 .

The steps of a method or algorithm described in connection with the embodiments disclosed herein may be directly implemented in hardware, a software module executed by a processor, or a combination of the two. A software module may reside in a storage medium (ie, memory and/or storage) such as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, a removable disk, a CD-ROM.
