The IoT analysis firm, Berg Insight, reports that the number of urban air quality monitoring devices is forecast to increase from 73, 000 units in 2020 to 315, 000 by 2025. This serves as further evidence of the growing awareness in cities about limiting pollution and the need to monitor pollution in order to aspire to overcome it.

Berg Insight clarifies that: "This number refers to any type of networked outdoor air quality monitoring device that in some way is used for supplementary air quality monitoring purposes in cities and communities. Traditional regulatory monitoring stations and devices intended for personal use only are thus not included."
