AQMesh outdoor air quality monitoring system


A single AQMesh pod can monitor up to 6 gases as well as PM, noise and wind speed & direction with seamless data delivery and a range of power options.

All AQMesh pods are built to order at our UK factory, with a standard lead time of only 2 weeks, which includes our rigorous sensor characterisation and quality control process to ensure the best possible out-of-the-box accuracy.

Select your application below for recommended gas and PM specifications, or build your own with our AQMesh configurator.

Proven accuracy

AQMesh pods have been operating in real-world applications for the past decade. Across six continents and in all seasons, AQMesh pods have experienced some of the harshest conditions and environments around the world. By co-locating AQMesh pods with certified reference instruments in these real-world conditions, a wealth of datasets and working knowledge of the sensors has been collected, pushing AQMesh accuracy and reliability further than any other small sensor manufacturer.

Our PM sensor has MCERTS Indicative certification for PM2.5 and PM10 with either a heated or unheated inlet, and our gas sensors have been meeting soon-to-be released CEN standards for years. Whilst the US EPA has stated it won’t offer certification for small sensor systems, it has offered targets for such devices, which AQMesh has been meeting for years.

AQMesh is also verified in a variety of independent trials and academic trials and studies, been trusted by hundreds of users around the world as well proving the legitimacy of small sensors for smart cities and leading the way for small sensor certification.

A few benefits of AQMesh

  • Accurately measure the target pollutant

    Meaningful correction of cross-gas effects and interference from environmental conditions is consistently delivered through proven and traceable processing.

  • Data management flexibility

    AQMesh processes and stores all readings on its bespoke secure server which can be accessed by a website login or API to integrate with other systems, or it can be simple emailed to you at your preferred schedule.

  • Data secure and accessible on the cloud

    With measurements processed and stored on the secure AQMeshData server there is no need for site visits to retrieve data and should anything untoward happen to the pod, data is still perfectly safe and accessible. The on-board buffer ensures no data is lost if comms are interrupted but cloud processing keeps hardware power demands to a minimum.

  • Easy to install

    AQMesh pods are neat, compact and easy install within just a few minutes and experienced technical staff are not required. A 90 second installation video shows just how quick it is to be up and running.

  • Low cost of ownership

    AQMesh pods require very little maintenance and there is a very low ongoing cost. All we recommend is the electrochemical sensors are replaced every two years, and we replace all sensors for free during the first year.

  • Maximum uptime across the network

    Robust hardware, wireless communications and the secure AQMeshData server mean AQMesh pods can easily reconnect themselves and continue to capture data if power is ever interrupted. Faults or failures can be detected, diagnosed and resolved swiftly and remotely, without the need to visit the equipment.

AQMesh applications

  • Mining


    Whether you’re a mining operator or a consultant offering monitoring services to your mining clients, AQMesh offers a robust, versatile and reliable solution for air pollution monitoring across the site and along the site perimeter.

  • Fenceline monitoring

    Fenceline monitoring

    Fenceline monitoring – or perimeter / boundary monitoring – is the process of monitoring emissions from industrial facilities along the site’s boundary, in order to ensure that any pollution from the site’s operational activity are either not escaping off the site, or if they are they are not exceeding any regulatory limits.

  • Industrial emissions

    Industrial emissions

    The impact of the industrial and manufacturing sectors on the environment has never been more of a priority. Reducing their effects on air quality due to pollutants such as nitrogen oxides, sulphur dioxide, particulates and VOCs are a key focus for many organisations and regulatory agencies.

  • Construction


    Air quality monitoring is the process of monitoring ambient pollutants, particles and dust from construction sites, in order to ensure that any pollution from the site’s operational activity are either not escaping off the site, or if they are they are not exceeding any regulatory limits.

  • Government & local authorities

    Government & local authorities

    Monitoring air quality is essential for authorities to ensure pollution levels in the area do not exceed regulatory limits. The air quality data gathered can be used to identify pollution sources, as well as develop strategies and inform policies to manage levels of air pollution and mitigate its impact on the health of the population.

  • Research & consultancy

    Research & consultancy

    Consultancies and research facilities are working with partners throughout the world to provide air quality monitoring and management services.

  • Transportation


    Transportation is one of the largest contributors to a reduction in air quality, especially in urban areas, producing many pollutants including nitrogen oxides, particulates and noise from roads, airports, rail networks and ports.

Featured case studies

Featured news

  • Supporting your air quality monitoring system when you can’t get to it

    Each time we think we have found a spectacularly remote monitoring location, an even more inaccessible spot is reported by one of our users. Full-day trips to visit a location have now been beaten by customers who need to charter a plane to reach them. So, remote diagnostics and support are very important.

  • Anodes and anemometers for harsh winter air quality monitoring

    We are often asked by customers whether AQMesh can operate in cold conditions. Long-term use at temperatures well below freezing, with ice and snowfall, is indeed challenging.

  • Check H2S, SO2 and VOC emissions continuously around your sites

    If you are responsible for air pollution around an oil, gas or industrial site, you have a range of options at different price points. AQMesh offers a cost-effective way to continuously monitor ambient air quality, as frequently as every minute, with readings accessed securely online and user-settable alerts.

  • UK local authority uses AQMesh for cost-saving NO2 monitoring network

    A UK local authority installed nine AQMesh systems at different points across a busy town, measuring nitrogen dioxide (NO2) at 15 minute intervals, monitoring 24/7. These locations were established monitoring points, where measurements had been taken previously using diffusion tubes, limited to one average reading every few weeks.

  • Six hidden costs to look out for when choosing a small sensor air quality monitoring system

    Anybody in the market for purchasing a small sensor air pollution monitoring system will need to consider budgets, but it’s not always obvious how the products being reviewed actually compare across their full operational life. 

  • Solar power supplies are not all equal for full-year, consistent AQ monitoring

    Autonomous power can make all the difference in hyper-local air quality monitoring. With particulate matter sampling needing a little more power than passive gas sensors, solar is the go-to power option, rather than internal battery. Most systems require sufficiently little energy that they can be powered by a relatively small solar panel, but it’s the back-up power management that makes all the difference.
