AQMesh pods are neat, compact and easy install within just a few minutes and experienced technical staff are not required
Multisensor mini air quality monitoring station
AQMesh pods can measure just one gas or up to six gases, particles, noise and wind speed & direction. Humidity, pressure and pod temperature are always measured.
“You can measure all that with just one unit?” is a common exclamation when potential customers are presented with an AQMesh pod. It is very convenient to be able to install and manage a wide range of sensors in a single piece of hardware and maybe even more so to have access to each of those data channels, with a common time stamp, delivered together. Watch out for similar products which theoretically offer a wide range of measurements but actually are quite limited about what can be measured by a single unit.
So what is the point measuring so many pollutants? For a start, offering temperature, pressure and RH% as standard offers useful metadata, as well as environmental measurements in their own right. We regularly look at temperature measurements of co-located pods to identify local issues that may be affecting data. Although your interest may primarily be in a single measurement (such as NO2) taking other measurements alongside (such as CO2) can provide context and even insight into pollution sources to help ensure that the correct conclusion is drawn from changes in pollutant levels.
Related to this, choosing the AQMesh wind speed and direction sensor as an option provides key information alongside pollution data. Analysing pollution with reference to wind speed and direction can increase the information about local and distant sources, understanding local pollution distribution, and allow the largest possible area to be meaningfully monitored with the smallest possible number of measurements nodes.
More AQMesh benefits
With wireless communications using the global mobile network and a choice of power options, including batteries, mains supply or a bespoke solar pack, AQMesh can be installed in almost any location
Meaningful correction of cross-gas effects and interference from environmental conditions is consistently delivered through proven and traceable processing
Whilst some manufacturers use a calculation to give an NO2 reading, AQMesh uses a unique O3-filtered NO2 sensor for accurate, direct measurement of NO2
AQMesh has been on the market and in the field since 2012, with some customers still successfully operating the exact same pods they received nine years ago
The carefully developed data processing algorithms used by AQMesh are fully traceable and fixed by version number, and, unlike other systems, have been achieved with no use of machine learning or artificial intelligence

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.
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.
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.
Small sensor air quality monitoring devices can be mounted flexibly, offering localised air quality information and data analysis, but they vary in what they can measure, how accurately they measure it, and how readings are accessed by users. Critically they also vary in terms of the reliability of data delivery.
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.
