Abstract
Digital signage units for generating air quality related alerts and providing advertising images and/or wayfinding are disclosed, along with related systems and methods. The digital signage unit includes an air quality monitoring device located along an open loop pathway for ambient air. The air quality monitoring device includes sensor(s) and receives air characteristic measurement data from the sensor(s), where the air characteristic measurement data indicates a concentration for each of certain compound(s). Where the concentration of any one of the compound(s) exceeds a respective predetermined threshold, content displayed at an electronic display of the digital signage unit is modified to include displaying an alert.
