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

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

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. A small sensor air quality monitoring system or network can be a significant purchase, so whether project-based or with ongoing monitoring in mind, it is likely that the equipment will be in use for several years. There are six main areas of cost highlighted here, all of which kick in after initial purchase.

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

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.

A rural air quality saga

A rural air quality saga

We installed an AQMesh pod on a rural road to see the impact of local road closures and increased traffic but we left it in place and have been able to monitor how the air quality changes from autumn to winter. This time covered changing traffic patterns, wood-burning, bonfire night, the Christmas break and then no traffic, with the road closed by floods. So, what did we see?

What area does an air quality sensor system cover?

What area does an air quality sensor system cover?

Generally, the limiting factor will be budget. The clue is in the name with hyperlocal air quality monitoring, and pollution levels can vary hugely over short distances. NO measurements around streets, for example, are often significantly different from one side of the road to the other, particularly if there isn’t much wind and/or a street canyon effect.

AQMesh can also be scaled using diffusion tubes

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.
