Innovative Digital Display Board for Real-time Air Quality Data

Air quality affects people health, whether outdoors or indoors. It’s essential to disclose the real-time status of urban air quality in public areas, such as schools, hospitals, malls, offices, etc. So that people can grasp the information and take proper action according to a health guideline.
Designed by Edimax, the SB-1002W Signal Board is an innovative digital display board under the Total Air Quality Solution product series. It intuitively displays the concentration of ambient air quality data in an apparent visual sign. Not only providing the value per pollutant types, but the SB-1002W’s distinct LED colors will also vary by degrees to highlight the air pollution levels.

Variable Color Display Calls for Attention

Six grades air quality levels indicators from Good to Hazardous, four colors indicator for recommend action.
