Description

AQ Guard Smart is a compact and cloud-ready measuring instrument for the determination of ambient air quality. In addition to the measuring principle of optical scattered light measurement of single particles based on the technology of the EN 16450-certified Fidas® 200 for fine dust measurement.

The MCERTS qualification for the AQ Guard Smart has been confirmed by TÜV. The certificate has been applied for.

The system is designed for the requirements of outdoor air measurement in the smart city environment to improve granularity while maintaining high comparability to official measurements, for environmental monitoring and health protection.

Thus, the AQ Guard Smart supports model calculations of the current fine dust pollution and forecasts, which will require stricter limit values in the future and thus the necessary lower uncertainties for local measurements. Seasonal and cyclical particulate matter forecasts can be carried out in a more differentiated manner and with higher accuracy. This enables timely planning of measures to prevent particulate matter pollution and protect health, differentiated implementation of measures to protect the population, and implementation of abatement strategies to reduce pollution, e.g., through predictive traffic control.

For a better understanding of the fine dust input and its cause, the device is optionally available with a corresponding weather station, which provides supplementary meteorological information. Sensors that measure temperature, humidity and pressure are integrated as standard.

The AQ Guard Smart is the most modern, continuous air quality measurement system available, which also offers manufacturers and users of lower-resolution sensors a comparison option and thus a plausibility check before the measured values are made available for further processing in formation and dispersion studies.
The cloud application MyAtmosphere created for this purpose enables both private and governmental operators to retrieve current measured values directly, to compare them with other devices without delay and further processing, or to integrate them into their own systems/environments via an optional programming interface (API). It speaks for itself that the usual protocols such as ASCII, MODBUS via TCP or UDP are also integrated.
