AQ Guard Smart is a compact and cloud-enabled measuring device for determining air quality. In addition to the measuring principle of optical scattered light measurement on individual particles based on the technology of the EN 16450-certified Fidas ® 200 for fine dust measurement, it uses further gas sensors for measuring the pollutant gases NO 2 , SO 2 , O 3, CO are integrated, which can provide information about the origin of the particles. The system is designed for the requirements of outdoor air measurement in the smart city environment to improve granularity while at the same time being able to compare with official measurements, for environmental monitoring and health protection. The simultaneous measurement of the noxious gases predestines the device for measurements in environmentally sensitive areas, especially where measurements of the noxious gases are already common or required by law.
The AQ Guard Smart received MCERTS certification as an Indicative Ambient Particulate Monitor on June 26, 2022 .
The AQ Guard Smart thus supports model calculations on the current fine dust pollution and forecasts that will require stricter limit values in the future and thus the necessary lower uncertainties for local measurements. Seasonal and cyclic particulate matter forecasts can be carried out in a more differentiated manner and with greater accuracy. This enables the timely planning of measures to avoid fine dust pollution and to protect health, the differentiated implementation of measures to protect the population and the implementation of avoidance strategies to reduce pollution, e.g. B. through anticipatory traffic control.
