Air Quality Sensor Technologies Explained: OPC, Electrochemical, NDIR, PID and MOX
Understand how OPC, electrochemical, NDIR, PID and MOX technologies are used in continuous sensor-based air-quality monitoring, what their outputs mean, their main limitations and how to select a fit-for-purpose approach.
Continuous Environmental Noise Monitoring: Applications, Data and Limits
Understand where continuous environmental noise monitoring fits, what long-term and distributed measurements can reveal, and when a more specialised acoustic assessment may be required.
Municipal Weather Monitoring Networks: Temperature, Rainfall, Wind and Local Environmental Data
Learn how municipalities can design local weather monitoring networks for temperature, rainfall and wind, with practical guidance on siting, data quality, integration and operational use.
Budgeting for Air Quality Monitoring Networks: What to Consider
Air quality monitoring network cost goes well beyond device price. Use this TCO framework to compare installation, power, connectivity, calibration, servicing, data, staff time and downtime.
Meteorological Data in Air Quality Monitoring: Why Wind, Temperature and Humidity Matter
Wind, temperature and humidity affect pollutant transport, atmospheric mixing and particulate behaviour. Learn how meteorological data adds context to continuous air-quality measurements without turning correlation into source attribution.
Indicative and Supplementary Air Quality Monitoring: Roles, Uses and Limits
Understand how indicative measurements differ from supplementary air-quality monitoring, what each evidence role can support, and how data quality, calibration and project purpose determine how the measurements should be interpreted.
Aernode Data Flow Architecture: Local Modbus, External Server and Aernode Cloud
See how Aernode data can be accessed locally through Modbus, transmitted directly to an external server or managed through Aernode Cloud, and how data state and processing differ across each path.
VOC Monitoring with Compact Sensors: MOX and PID Explained
Understand the main VOC measurement approaches, where compact continuous sensors fit, and how MOX and PID technologies provide different outputs for environmental monitoring.
