Breathe London - 100 AQMesh pods are used as stationary monitoring points in the groundbreaking Breathe London project.
AQMesh is a small-sensor air quality monitoring system for measuring outdoor and indoor air quality, offering real-time localised air quality information and data analysis. AQMesh pods measure key pollutants in ambient air using the best small sensor technology combined with proprietary data processing derived from extensive global comparisons with reference data. The product combines a robust hardware platform with wireless power options, GPRS communication, cloud-based data processing and secure online access. AQMesh pods are manufactured in the UK to an exceptionally high quality based on many years’ experience of developing environmental monitoring equipment for harsh environments and challenging international standards.
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
Power supply options
AQMesh offers a range of power supply options depending upon your monitoring requirements.
The bespoke AQMesh solar pack is our most popular choice, offering autonomous continuous power all year round.
Internal lithium batteries are useful for pods monitoring gases only.

Featured case studies
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.
The small sensor air quality monitoring world has moved on during the last three years and we have identified several new challenges and benefits relating to the continual development of air quality monitoring technology.
The results of the 2019 AIRLAB Microsensors Challenge* were revealed in Paris on 21st January and AQMesh was awarded the highest score for accuracy of all products presented for monitoring of outdoor air quality.
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.
An AQMesh pod used in the recent Citi-Sense project in Norway was returned to us at the end of the project, and we were surprised at the condition.
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).
North Americans will be well aware of the particularly harsh weather in the early months of 2019, but AQMesh has taken conditions in its stride. The AQMesh stated operating range of -20°C to + 40°C is backed up by long-term operation across a wide range of climates.
