The carefully developed data processing algorithms used by AQMesh outdoor air quality monitors are fully traceable and fixed by version number, and, unlike other systems, have been achieved with no use of machine learning or artificial intelligence.
Measure accurately across every continent
Development through extensive global co-location comparison trials in all seasons across each continent means AQMesh can operate in the widest possible range of environments and conditions.
There is simply no substitute for getting out there and testing the conditions. From day one we have not been afraid to see exactly what AQMesh can do – and to test its limits. We have welcomed the opportunity to work with partners across the world, over nearly a decade, and let them carry out independent analysis of data from pods co-located with reference stations.
Most often the results have been great: not only has the pod carried on operating, whatever the conditions, but the data accuracy has been maintained. There have been times during the development of AQMesh where we have come across conditions which highlight an opportunity for improvement in our processing and we have used that – in conjunction with as wide a base of comparison datasets as possible – to develop a new processing algorithm.
We have seen pods covered in snow in Sweden or Minnesota, scorching in the deserts of Iraq, in heavy rain in Asia or Scotland. Just look at the range of countries where AQMesh has been used. AQMesh has led the way in development of small sensor air quality monitoring systems - including the first to use a sun shield to minimise the impact of direct sunshine – and we will continue to do so.
More AQMesh benefits
AQMesh air quality monitoring system performance and long-term baseline stability has been proven over many years of independent global co-location trials against certified reference equipment.
With AQMesh outdoor air quality monitors, meaningful correction of cross-gas effects and interference from environmental conditions is consistently delivered through proven and traceable processing.
Robust hardware, wireless communications and the secure AQMeshData server mean AQMesh air quality monitors can easily reconnect themselves and continue to capture data if power is ever interrupted.
The AQMesh air quality monitoring system 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.
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 outdoor air quality monitor, data is still perfectly safe and accessible.
