Proven success with air quality monitoring

Bill Hayes

Air Quality Program Coordinator, Boulder County Public Health

"The Node-S is solar powered, has impressive battery life, and transmits data via cellular network. That means we could put these monitors anywhere that the sun shines and you can make a cell call. After the Marshall fire we installed a total of 22 monitors in the burn area. "

Vanessa O'Brien

Senior Sustainability Officer at Lincolnshire City Council

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.

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."

Michael Ogletree

Air Quality Technical Services Program Manager at the DDPHE

"Clarity provided an off-the-shelf solution that was easy to deploy. Clarity Nodes are easy to set up and after reviewing a co-location we had in place, the data was in line with our expectations. The flexibility in changing the data capture rate was key — I was able to remotely configure the nodes to collect data at a higher or lower resolution as needed."
