The AQMesh small sensor air quality monitoring system already offers flexibility of monitoring location – through independent power and communications – as well as high data quality and traceability.
Full range of parameters available
AQMesh can be specified to monitor a single gas or up to 6 gases, as well as PM, noise and wind speed & direction:-
Measures gases NO, NO2, O3, CO, SO2 and H2S using the latest generation of electrochemical sensors
CO2 monitoring with a NDIR sensor
Measures particulates PM1, PM2.5 and PM10 with a light-scattering optical particle counter
Noise monitoring with an omnidirectional microphone
Meteorological sensor for wind speed and direction measurement
Measures relative humidity, pod temperature, atmospheric pressure as standard

AQMesh is now able to offer CO2 and H2S within its range of gas options for local air pollution monitoring. The NDIR CO2 sensor, which can be offered within a single AQMesh pod alongside five other gases out of NO, NO2, O3, CO, SO2 or H2S, as well as PM1, PM2.5, PM10, temperature, pressure and humidity, has been developed to deliver a higher performance than those typically used for indoor air quality monitoring.
AQMesh has an impressive collection of global users and performance results measuring ambient air quality in applications ranging from traffic planning and urban hotspots to industrial fence line monitoring.
The emergence of sensors capable of measuring the gases and particles that make up air pollution, especially in cities and industrial areas, has driven many academic studies which evaluate the sensors and compare performance against reference methodology.
AQMesh has been measuring ozone (O3) using small sensors since 2011 and the readings from the latest generation electrochemical sensor, using AQMesh v4.2.3 processing, as compared to co-located certified reference readings, consistently show an R2 of over 0.9 with an accuracy ±10ppb (20µg/m3).
Whilst not the only AQMesh pods still in regular use since the product was commercially launched in 2013, two AQMesh pods are still in use in Spain and demonstrate the long life of this small sensor air quality monitoring system.
AQMesh case studies
AQMesh is in use across the globe, with deployments in each continent in a wide range of projects. There are smart city networks in the UK and USA, tunnel ventilation systems in France, volcanic emissions in Myanmar and domestic cooking studies in Kenya to name a few, amongst many other outdoor and indoor air quality monitoring applications. A wealth of information on AQMesh projects and customers can be found in all our news items but here are a few examples of specific case studies.
Breathe London - 100 AQMesh pods are used as stationary monitoring points in the groundbreaking Breathe London project.
Urban Observatory - AQMesh systems are deployed across Newcastle and Gateshead in conjunction with other instruments for monitoring parameters such as air and water quality, noise, weather, energy use and traffic.
Minnesota Pollution Control Agency - 50 AQMesh pods are installed in Minneapolis and St. Paul to build up a picture of air quality across the two cities.
UNRESP project - Six AQMesh pods are used to show variations in volcanogenic emissions across locations near the Masaya volcano, Nicaragua.
AtmoSud & CETU - AQMesh network will be used to manage Marseille tunnel ventilation systems.
