Outdoor Air Quality Monitoring Station

Aernode is a configurable multi-pollutant outdoor monitoring system. Every station includes air temperature, relative humidity and atmospheric pressure. Depending on the project configuration, the Core Sensor Board can add particulate matter (PM10, PM4, PM2.5 and PM1), CO2, T.VOC Index and sound level measurement.

The Sensor Deck extends the station with gas sensing options including NO2, O3, CO, SO2, NO, H2S, NH3, CL2, HCl, HCN, H2O2, PH3, ETO and PID-based VOC measurement. Compatible external meteorological sensors can also be connected.

Aernode Lite and Aernode Pro use the same outdoor base station and Core Sensor Board. The difference is in the Sensor Deck: Aernode Lite supports configurations with up to four sensing elements, while Aernode Pro supports up to eight.

The two versions also differ in the range of compatible gas sensing options, allowing the station to be configured from compact multi-pollutant deployments to more advanced multi-gas monitoring projects.

Yes. Aernode uses a modular sensing architecture, so the measurement configuration can be selected according to the pollutants of interest, expected concentration ranges, environmental conditions and objectives of the monitoring project.

The most appropriate configuration should be defined project by project rather than by maximizing the number of parameters, because sensor technology, sensitivity, cross-sensitivities, operating life and maintenance requirements can differ significantly between applications.

No. Aernode is intended for continuous indicative and supplementary air quality monitoring and is not designed to replace regulatory reference monitoring stations.

It can complement existing monitoring networks by increasing spatial and temporal coverage, supporting operational analysis and identifying trends or events in locations where reference instrumentation would not normally be deployed. Project configurations can be designed with reference to the data-quality objectives established for indicative measurements under Directive (EU) 2024/2881.

Aernode is designed for rapid outdoor deployment. A typical installation requires a suitable mounting point, a 5–15 Vdc power supply and the communication option selected for the project.

Stations can be installed on walls, poles, public-lighting structures, urban furniture, building facades or dedicated tripod supports. Where mains power is unavailable, an autonomous solar panel and battery kit can be used. Cloud-connected installations also require suitable cellular or Wi-Fi connectivity.

Yes. Aernode measurement data can be accessed locally through Modbus RTU (RS485). Local data output can be used either independently or in parallel with transmission to Aernode Cloud.

The local interface provides raw measurement data: the station performs the electrical signal processing and basic on-device compensation required to produce the local output, while the complete centralized post-processing and data-management workflow is handled in Aernode Cloud. If a project uses local data only, any additional downstream processing, storage and integration logic must be implemented by the interconnected system.

Aernode stations are delivered with manufacturer calibration information and an additional second-level calibration performed in the Aernode laboratory.

For long-term monitoring, site-specific performance characterization and periodic recalibration should be considered according to the pollutant, sensor technology and project objective. Available approaches include co-location with a reference station and bottled-gas procedures for compatible gas sensors. The appropriate method and frequency depend on the required data quality, local environmental conditions and available reference data.

Service and replacement intervals should be defined according to the sensing technology, pollutant, environmental conditions, exposure and performance requirements of the project. Gas sensors typically have shorter and more application-dependent operating lifetimes than the sensing technologies installed on the Core Sensor Board.

Aernode therefore uses replaceable Sensor Kits so the Core Sensor Board and Sensor Deck can be maintained independently. Complete preconfigured assemblies can be exchanged in the field to reduce downtime, while component-level servicing can be performed in the laboratory when appropriate.
