Proven success with air quality monitoring

Julie Orth

Class Teacher, Sierra Waldorf Elementary School

"Having the Node-S air quality monitoring device on site is great for our school and a nice service to offer our surrounding community. Our device went in about 3 years ago and is working great! It is so important for us to know our air quality. Whenever it hits unhealthy levels, we keep our students inside. The data is available right on my phone, so I can check it ahead of recess and make a real-time decision on whether to send students outside or keep them on an indoor activity schedule when air quality is over the threshold.

Tomislav Andreev

Head of Environmental sector for the city of Strumica, North Macedonia

“With Clarity's hyperlocal network, we can begin to provide a more complete picture of how air pollution is occurring in a given micro region, and what preventive actions we need to take to minimize exposure. We can also measure the effectiveness of each activity taken by measuring concentrations BEFORE and AFTER that activity. This encourages us to think about policies that we want to change. It raises citizen awareness and creates a narrative that influences positive change. We need to know what the air is like NOW AND IMMEDIATELY, at each MICRO location, to react IMMEDIATELY, and to sanction those who are disrupting our health, the future of our youngest, and the future of our country. Every citizen of the municipality of Strumica has a strong ally in such innovative technology."

"The data provided by the sensors helped to speed up the city’s decision-making. Today, the sensor readings have had a direct impact on public opinion. This year, we launched public ecological transport and eco-taxi, and we are launching a new system of dedicated public transport lanes that will directly affect the transition to eco-friendly modes of transportation.”

“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.”

Air Quality Consultant and former Executive Director, Groundwork Richmond

"We couldn’t have done it with any other air quality monitoring solution. With their unique ability to operate off-grid, Clarity’s Node-S provided the ability to site our air quality monitors in the locations that mattered most to community members in Richmond. The data are reliable, real-time, and hyperlocal, and our network is now being used as a blueprint for AB 617, a landmark regulation that empowers communities to take control of air pollution."

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.”
