Airly Pure PM Sensor for hyperlocal air quality monitoring

Airly Pure PM Sensor
Built for performance. Trusted for precision.

Airly Pure is a best-in-class, certified PM sensor that measures PM1, PM2.5 and PM10 with accuracy and reliability. Designed for effortless deployment anywhere, it operates independently via GSM connectivity and can be powered off-grid using solar panels. With seamless access to data through the Airly Data Platform, it’s the go-to solution for local authorities, businesses, and partners who need effortless, scalable air quality monitoring without infrastructure headaches.

"Having Airly systems available to us has allowed our customers to thrive in an extremely competitive market space. These tiny systems, complete with MCERTS certification, have been responsible for hundreds of project wins. The key reason is their size - being able to provide and install systems that effectively disappear on-site helps prevent theft and unwanted attention. The partnership between Acsoft, Svantek, and Airly works so well because the teams share the same drive and culture. We all just want to provide the best data to our customers, protect the environment, and save time and money along the way!"
