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.

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.

How do you calibrate a small sensor air quality system?

How do you calibrate a small sensor air quality system?

First of all, you can’t calibrate using bottled gas, as with reference analysers. Even if you can create a chamber or manifold to pump gases through, electrochemical gas sensors do not respond in the same way to single, dry gases as they do to mixed gases in an ambient environment.

AQMesh delivers accurate PM coarse measurement with customisable alerts

AQMesh delivers accurate PM coarse measurement with customisable alerts

Many small sensor air quality monitoring systems cannot reliably measure coarse particulate matter, or PM10, because of the technology they use. AQMesh’s proprietary optical particle counter (OPC) delivers high out-of-the-box accuracy across all key particle matter (PM) fractions thanks to its bespoke, in-house design.

Local air quality data secure and accessible?

Local air quality data secure and accessible?

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.
