Five AQMesh pods are currently installed around Keflavic airport in Iceland to monitor gases produced by the nearby volcano at Fagradalsfjall, including hydrogen sulphide (H2S), sulphur dioxide (SO2) and nitrogen dioxide (NO2).

A UK local authority measured the difference in local air pollution levels when reopening roads that had previously been closed for social distancing purposes as part of Covid-19 mitigation efforts.

Two AQMesh pods measuring airborne particulate matter have been loaned to the University of Cambridge, ahead of the COP26 meeting in Glasgow, to support research into measurement of particulate matter.

AQMesh is now being supplied and supported directly in the UK, as a positive step towards providing fast, direct manufacturer support. The UK-based manufacturer has already been supporting global users directly since the product first launched ten years ago and is now extending that same support to UK customers.

Ecotec International Holdings, LLC (“ECOTEC Group”), owner of Environmental Instruments Ltd., the manufacturer of AQMesh, is pleased to announce the acquisition of Gas Data Limited and its parent company, Innovational Technologies Limited, which is expected to strengthen the state-of-the-art portfolio of highest quality gas detection, gas analysis and air quality monitoring solutions.

Whilst there may be a growth in city-wide communications integration, “big data” and public interest in local air quality, the challenges of monitoring complex atmospheric chemistry have not changed. Integrating “sensors” can sound straightforward but information about air quality around a city must be handled carefully.

A collaborative research project between City of Kitchener, Wilfred Laurier University and Hemmera Envirochem Inc, which uses AQMesh pods installed across Kitchener, will be presented at the Pacific Northwest SETAC Annual Conference in the USA on April 15th-16th.

AQMesh has announced this week that all new pods will receive a free 5-year manufacturer’s warranty, as opposed to the standard 12-month guarantee. The new 5-year pod warranty underpins years of proven product quality.

The new AQMesh LTE CAT M1 modem uses the latest LTE (Long Term Evolution) communications standard, including support for NB-IoT (machine-to-machine).

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.

Refinement and development of the AQMesh small sensor air quality monitoring system over many years, and through numerous global co-location comparisons, brings a wealth of unique benefits.

The Breathe London project has this week released a 3D data visualisation story created by the Environmental Defense Fund Europe and Google.

In 2015 a team from the University of Bonn began monitoring air quality around the Geiranger fjord, Norway. In this pilot study pollutant gases were measured using AQMesh, as well as particulate matter. From 2016 the team installed AQMesh pods at different points around the Fjord.

Breathe London preliminary analysis results reveal substantial NO2 pollution reductions after the UK government implemented restrictions to reduce the spread of Covid-19, particularly after social distancing was strongly encouraged on 16 March.

Technology is critical to so many essential services during the current global COVID-19 crisis, but it is also allowing local air quality to continue to be monitored, in real-time, across the world. Small sensor air quality monitors such as AQMesh pods can use cloud data storage to ensure that air quality information is stored and accessible even when staff are not able to visit equipment.

Mining applications in Southern Africa which use AQMesh include copper, phosphate platinum and coal extraction and handling. Typically the mining client will set up a network of pods to monitor in key locations around the perimeter of the facility, potentially including nearby sensitive zones, such as schools.

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.

Few people know how clean the air is where they live, work, exercise or where their children go to school. Although air quality can be shown to vary significantly over short distances, air pollution is generally measured using a small number of large, expensive and high quality monitoring stations.

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.

On Sunday 13th May 2018, Cardiff Council organised a car-free day in the city’s central area. As a result of this event air quality monitoring data showed an average 69% drop in nitrogen dioxide (NO2) – one of the pollutants of greatest public health concern.

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.

Extensive research has shown that indoor air quality is often worse than outdoors. Closed system buildings trap harmful particles inside, and external air intakes can bring in more polluted air from outside.

Minnesota Pollution Control Agency (MPCA) has purchased fifty AQMesh pods to measure key air pollution gases and particulate matter across fifty different zip code areas.

The team at AQMesh continue to receive many enquiries from smart city initiatives and are concerned that integrators risk undermining entire projects by distributing meaningless or misleading air quality information.
