"The impact of the project has been great in the sense that we have revolutionized the air quality landscape, and the Clarity air quality sensors have been instrumental to the impact that we have achieved. The citizenry is now more aware of air pollution issues. We started the mother project in 2019 when not a lot of the population was aware of air pollution. With Clean Air Fund coming into the landscape and supporting projects like ours, we’ve been able to create more public awareness."
“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."
It has been great to be able to work with such a large number of students and share live local air quality data with them. All the schools have seen the benefit in understanding what the data is telling them, and how this can be used to inform decisions about how and when to travel.

"People want to know what’s really happening with their local air quality. The ability to have an answer back to students, parents, and teachers within seconds is invaluable."
We work mainly with the local authorities for deploying the Node-S devices — with the local council. The community has been really helpful and has made a big difference. The majority of the Nodes are up on street lamps around the town.
"Having real-time, very hyper-local data about the air quality where you are spending your time has great potential to impact people, in terms of the decisions they make, but also in terms of making that connection between the environment and health."
“The Know Your Air Network provides us with vital air quality information that can be used to inform real-time decisions to protect the health and well-being of our school communities. This air quality sensor network is unparalleled in its size and scope, demonstrating Los Angeles Unified’s commitment to providing the safest learning environment for our students.”
"Having the sensor 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. "
“We chose Clarity because they provided up-to-date, local, scientifically-backed, and relevant data to make decisions about whether to keep students inside. Because of the geography and demographics in our county, the official air monitoring stations are about an hour away with hills in between, providing irrelevant data. We would have poor air quality and the official stations would be cleared; or the official stations would show heavy particulate levels and we would have clean air."
Air quality guidelines for schools — know when to switch to indoor activities
On days when air quality is very poor, schools are recommended to enforce indoor activity schedules. Monitoring AQI levels at your school and following outdoor physical activity guidelines is one of the most effective ways to protect students.

Reduce absences and improve academic performance by managing air quality in schools
Reduce absences and protect student health
Studies have found that a single day of unhealthy air quality can more than double absences. Absences come at a cost to both schools, and students' families.
Improve academic performance
Exposure to outdoor air pollution can inhibit cognitive development and negatively impact academic achievement. Studies have found air pollution levels to be a statistically significant predictors of student performance.
Make better decisions with real-time air data
Air quality can change rapidly, making it important to have access to real-time air quality data when making operational decisions. Monitoring air quality ensures you make the right decisions for student health.
Drive positive impact your community
You can have a broad positive impact on your community by providing real-time air quality data and educate students and parents on how to minimize their exposure.
Frequently Asked Questions
Children are especially vulnerable to air pollution, which can trigger asthma, impair lung development, and affect cognitive performance. Monitoring air quality on school campuses helps districts protect student health, make informed decisions about outdoor activities, and build community trust.

Yes. The Clarity Node-S air quality sensor is solar-powered, low-profile, and weatherproof—ideal for unobtrusive installation on rooftops, fences, or poles. It operates without needing on-site power or internet, making it safe and easy to deploy on school campuses.
Districts use real-time data to make daily decisions about recess, athletic practices, or HVAC usage. Over time, the data helps identify pollution trends and guide infrastructure upgrades or traffic mitigation near schools. Data is visualized via the Clarity Dashboard and can be shared publicly with parents.
Absolutely. The Clarity Dashboard is designed to be intuitive for non-technical users, with color-coded AQI indicators, maps, and simple charts. School staff can quickly assess current conditions, set alert thresholds, and download reports—no data science degree required.
Yes. Schools can configure Air Quality Alarms to receive email or SMS alerts when pollution exceeds defined thresholds, such as during wildfire smoke or high-traffic hours. Alerts help staff take timely actions like moving recess indoors or notifying families.
Yes. For example, Adams County, Colorado partnered with Clarity to install sensors at schools through the "Love My Air" program. These installations provided local data for environmental education and supported EPA-funded community health initiatives.
Air quality data can be a powerful STEM teaching tool. Students can explore pollution trends, analyze patterns during wildfires or rush hour, and even conduct their own experiments. Clarity’s public-facing OpenMap makes it easy for classrooms to access and engage with local environmental data.
