AQMesh air quality monitoring systems can measure just one gas or up to six gases, particles, noise and wind speed & direction. Humidity, pressure and pod temperature are always measured.
NO2 measurements you can rely on
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.
It is true in general that small sensor system air quality system customers should be on a sharp look-out for “inferred” measurements, as opposed to direct measurements, because there is a lot of it about. Specifically regarding NO2 measurement, the cross-interference from O3 is well known and indeed was a limiting factor in the use of electrochemical sensors in the early stages of AQMesh development. The latest electrochemical sensor used to measure NO2 in AQMesh feature a filter to remove O3 from the air sample at the sensor interface and is highly effective, over at least the two-year recommended sensor life. In theory the filter can be exhausted during use but the levels of O3 which would be necessary to do this fall far short of the typical exposure that any sensor is likely to have in years of real-world measurement.
As well as delivering a reliable two-year NO2 sensor life, the O3 filter offers proven performance over this period, with no measurable degradation of performance or “drift”.
More AQMesh benefits
The AQMesh air quality monitor is neat, compact and easy install within just a few minutes and experienced technical staff are not required.
With wireless communications using the global mobile network and a choice of power options, including batteries, mains supply or a bespoke solar pack, AQMesh air quality monitors can be installed in almost any location.
The AQMesh air quality monitoring system 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.
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.
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.

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.
AQMesh performance has developed through a series of co-location comparison trials in which AQMesh pods are installed next to an air quality monitoring reference station..
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.
AQMesh has been independently tested and verified in numerous academic studies and publications
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.
