The AQY 1 is designed to be used as a single device or deployed in a network of monitors in an urban environment. Small, cost effective, and user friendly it can be used by air quality professionals and those who are new to the science of air quality measurement.

The AQY monitor itself is small, about the size of a two-slice toaster, and measures the following parameters:

     -Particulate matter (PM2.5 & PM10)

     -Ozone (O3)

     -Nitrogen Dioxide (NO2)






     -PM2.5 and PM10 optical particle sensor (0 to 1000 μg/m3) with RH correction

     -Ozone (0-0.2 ppm O3) GSS gas sensor with integrated zero cycle

     -Nitrogen Dioxide (0-0.5 ppm NO2) gas sensor with O3 interference correction

     -External temperature and humidity sensor, with calculated dew point

Life expectancy

System: 5 years Sensors: ~12months based on 0-50 μg/m3 annual average PM10

Other measurements

Temperature: -40°C to 125°C; Relative Humidity: 0 to 100%; Dewpoint: -30°C to 50°C


Installation and Maintenance:

The AQY 1 air monitor mounts to walls, poles or railings using a supplied mounting bracket or simply with cable ties. Weighing approx. 1kg, the AQY 1 is intended to operate in a fixed location yet it can be moved from place to place with relative ease.

Power is mains-supplied via a 12VDC outdoor-friendly plug pack. Solar and battery power is possible, though not currently available as a factory-standard option.

Once installed the AQY is designed to be trouble-free. In moderately polluted conditions the AQY 1 will not require maintenance for more than 12 months. Using Aeroqual’s software tools, the sensors can be remotely calibrated to extend their useful operating life. When sensors do expire, replacement is simple and can be carried out by an authorized service center or by those who are confident to do so themselves.


Software and Communication:

The AQY 1 comes with the same air monitoring software package as our professional-grade AQM and AQS products. The software is browser-based and allows users to view multiple monitors on a map, average data, plot charts with multiple monitors and parameters, and manage them remotely – e.g. trouble-shooting, changing settings, updating firmware. For more information on the air monitoring software visit this page.

The AQY 1 communicates wirelessly via WIFI or 3/3.5/4G cellular. The AQY 1 has on board storage to ensure no data ever gets lost. In addition, data can be downloaded directly from the monitor if required, which is handy in case you lost your internet connection for example. Advanced users may prefer to access their data through our API, so they can view and analyze data in their preferred software package. All options are available with the AQY monitoring system.


Care Support Package:

The CARE Support Package includes:

     -Cloud Plus software license for data mangement, diagnostics and reporting

     -Open API for access to data

     -Remote technical support and instrument health monitoring

     -Unlimited data backup and storage

     -Free automatic upgrades to the latest version of Connect and Cloud software

     -30% off replacement parts and sensors
