Proven success with air quality monitoring

Bill Hayes

Air Quality Program Coordinator, Boulder County Public Health

“I’m now able to see where each one of my monitors is. The color of the dot tells me what air quality it’s currently recording. I can then click on any one of those individual monitors to get more information.”

Bolat Amirgaliyev

Head of Environment Division, EcoAlmaty

"Today we have 50 Clarity Node-S sensors in Almaty that provide us with online data on the type of particles and pollution in different parts of the city. Thanks to these sensors, we can plan environmental measures in Almaty.”

Dr. Ian Longley

Principal Scientist - Air Quality, National Institute of Water and Atmospheric Research

"We needed high-density data to develop a model that was representative of a real situation on a very local scale – so multiple devices and multiple locations. The Clarity Node-S was ideal for this use case."

Kostadin Kostadinov

Mayor of the Municipality of Strumica

"We have installed Node-S sensor monitors at 3 locations to detect sources of air pollution. What does this mean? This means that every citizen of the municipality of Strumica is an inspector from today and will be able to monitor concentrations of PM2.5 particles from the sensor monitors, and this application will also be implemented in the Inspection Services of the municipality of Strumica, where air pollution will be monitored around the clock, and they will be able to react quickly to sanction negligent polluters. After electrified public transport and bicycle paths, with this innovative project, we prove that we are seriously investing in reducing air pollution in Strumica."

Technical Lead, Mobility and Sustainability Projects, Royal Automobile Club of Western Australia

“What we are expecting from the Black Carbon Module is three things. First is to evaluate black carbon concentration levels in Perth. Second, currently there’s no regulation in Australia for black carbon, so the outcomes of our study could potentially lead us to advocate on this matter. And last but not least, if we identify that we have a black carbon issue in Perth, this module will allow us to know its source: is it coming from traffic emissions, is it coming from biomass? That will help us diagnose the problem, and so find what the best solutions to fix it could be.”

William Chevalier

Supervising Air Monitoring Specialist, Monterey Bay Air Resources District

"Clarity works very nicely for our wildfire air monitoring network. Their Node-S sensors are very quick to install and very easy to use, thanks to the native solar panel and cellular antenna. Not having to use somebody else's WiFI in a remote location is great — that had been a major issue for us with several projects.”
