AQMesh complements air quality modelling, reference equipment and indicative data sources

Leading small sensor air quality monitor, AQMesh, has recently been shown to work alongside passive samplers and air quality models, as well as complementing reference station networks. A recent study shows AQMesh calibration against diffusion tubes and two 2017 conferences have highlighted the potential of such systems used in an air quality network. At the … Read more >>

AQMesh can also be scaled using diffusion tubes

The AQMesh team has carried out a test which shows that calibration (scaling) of AQMesh against one, or ideally several, diffusion tubes, is a viable option when no local reference station is available. When three AQMesh pods and four NO2 diffusion tubes were co-located against a reference station, the diffusion tube readings were so consistent … Read more >>

Assess employee air pollution exposure with AQMesh

On 9th April The Sunday Times reported that employers have been told they are legally obliged to protect their staff from diesel fumes — and could be sued if workers develop cancer later in life. Read the full article here. Employers who want to assess risk to employees can use AQMesh to take round-the-clock readings of … Read more >>

Easy integration of air quality data for smart cities with AQMesh

Smart city projects pursue the vision of instrumenting a city with a large number of measurement ‘nodes’ and distributing this information to a range of stakeholders. But at that point different priorities emerge: IT teams are attracted by how readily data can be integrated and communicated whilst air quality professionals focus on how meaningful the air quality readings are. … Read more >>

AQMesh in BBC air quality feature

AQMesh showed its versatility in the BBC’s Inside Out feature on air quality (West region). The programme aired on 6th March but is available on iPlayer at until 5th April. AQMesh pods were used on the back of a bicycle and inside a taxi, to show the NO2 and particulate matter exposure experienced by … Read more >>

Value for money air quality sensors for smart cities

Smart city projects increasingly seek to include air quality measurements. If city authorities and the public are being asked to act based on air quality readings they must be credible. Whilst cheap sensors may offer easily integrated readings, they offer poor value for money if the information they produce cannot be trusted by the public, … Read more >>

AQMesh demonstrates legitimacy of small sensors for air quality in Cambridge

At the RSC AAMG event on ‘Air Quality Monitoring: Evolving Issues and New Technologies’ Professor Rod Jones of the University of Cambridge presented a paper showing very encouraging results. “Because we know that all the pods read the same and because we have a comparison between one pod and a reference instrument we can say … Read more >>

Crushed AQMesh pod still working perfectly

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. Despite the damage, this robust little pod was still working perfectly, with data still being received. AQMesh pods are able to measure up to 6 gases, including NO2 … Read more >>

AQMesh performance proven in independent study of air quality sensor systems

The Assessment of Air Quality Microsensors verses reference methods: The EuNetAir joint exercise has recently been published, and shows an R2 against for reference for AQMesh of >0.8 for NO2. Read the full study here. EuNetAir is the European Network on New Sensing Technologies for Air Pollution Control and Environmental Sustainability, working towards European-wide air … Read more >>

AQMesh solar unit gives flexible air quality monitoring

January, for many of us, is a surprising time to focus on solar energy but a new solar power unit designed specifically to power the AQMesh air quality monitoring system can power a full-specification pod throughout any western European winter. Lithium batteries established AQMesh as the first reliable ‘small sensor’ air quality monitoring device that … Read more >>
