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.

Why we love PAS4023

Why we love PAS4023

Is it normal to get excited about a Publicly Available Standard? For us it feels like a long time coming, and this first step on the long road towards an ISO standard for small sensor air quality monitoring is very welcome.

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.

Do air quality people love holidays more than everyone else?

Do air quality people love holidays more than everyone else?

Everyone loves holidays, whether Christmas or anything else, right? So what’s special about ‘air quality’ people? What we get so excited about are ‘free’ experiments, where distinct changes in activity help to peel away the layers of air pollution measured.

University of Cambridge measures seasonal variabilities in air quality in West Africa using AQMesh

University of Cambridge measures seasonal variabilities in air quality in West Africa using AQMesh

It’s great to see the team at the Department of Atmospheric Chemistry, University of Cambridge using their AQMesh pods for another project, this time in Lagos, Nigeria and Yaoundé, Cameroon.

Loads of AQ data = a good thing? Be careful what you wish for…

Loads of AQ data = a good thing? Be careful what you wish for…

Hyperlocal air quality monitoring promises to fill in the gaps between sparse reference stations – great, lots more measurements. And each of your lovely small sensor monitoring stations can measure a dozen or more pollutants and environmental conditions – even better. Or is it?

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.
