Proven success with air quality monitoring

David Broadhag

Technical Lead at RAC (Royal Automobile Club of Western Australia)

"Now that we have collected a couple of years of data, we are starting a new phase of our project, which is analyzing the data and drafting our first reports. Clarity is helping us put together two internal reports and two public reports. In terms of internal reports, the first one is purely technical and allows our team to be more efficient and proactive in the maintenance of our network. As an example, it allows us to have 95% of our sites with uptimes greater than 95%. The second internal report aims to support our public policy team to advocate and influence for taking actions for better and cleaner air in WA, Western Australia.”

"Air quality is a hidden issue in the sense that it's become so embedded in aspects of urban life in San Francisco. It can be a challenge for residents who have been living in the neighborhood for a long time to articulate what their air quality issues are. Some have just accepted it as a way of life.”

"Clarity was our first-choice air quality monitoring provider for several reasons. We enjoyed working with the Clarity team - they are highly knowledgeable and always responsive. The Node-S devices themselves are also incredibly resilient, which was especially important for us when deploying the monitors in emergency conditions during the wildfire events this past year."

“We're a nonprofit, so we don't have a ton of capacity to mess around with tech. Clarity Node-S devices are easy to deploy and solar-powered, so you can put them in parks, on rooftops, wherever — and they just work. We can focus on working with our community members.”

“Putting the power of air quality monitoring from institutions into the hands of communities is a game changer – every citizen, at any moment, can monitor air quality at any location in the city. Every politician must know that making decisions that improve air quality are standards that will protect us ourselves. Cooperation between local and central government is needed to determine an Action Plan for improving air quality. By implementing such a project in the municipality of Strumica, we have taken the first step (and the most important) towards such cooperation."

"The Node-S devices worked and the data was much better than other low-cost sensor data — Clarity pays attention to and cares about trying to get as accurate data as possible.”
