The Clarity Node-S air quality sensor:
Solar-powered and cellular-connected out of the box

Clarity’s flagship particulate matter (PM) and nitrogen dioxide (NO₂) monitor is self-powered, FCC/CE certified, UV-resistant, MCERTS-certified for use with solar power, and weatherproof. Our devices come pre-configured with integrated solar power harvesting, batteries, and global cellular connectivity — meaning you can get up and running quickly without external infrastructure.

A truly self-sufficient IoT air quality monitoring device, the Clarity Node-S accommodates site-specific requirements according to your needs, not the other way around. In fact, we’re so confident in the Node-S’s ability to amaze, our solution comes with free hardware replacements.

Air quality measurement equipment trusted by organizations like:

Andrew Grieve

Senior Air Quality Analyst, Imperial College London

"The Clarity Node-S is light, it has a small solar panel, and it's reliable. We can put them anywhere. All of those things combined mean it is super easy for communities to put them up by themselves."

Bill Hayes

Air Quality Program Coordinator, Boulder County Public Health

"After the Marshall fire we installed a total of 22 monitors in the burn area. 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 that you can make a cell call."

William Chevalier

Supervising Air Monitoring Specialist, Monterey Bay Air Resources District

"We were excited when we saw what Clarity was offering — it works very nicely for our objectives with the wildfire air monitoring network. We liked that Clarity’s sensors are very quick to install and very easy to use, thanks to the native solar panel and cellular antenna. Not having to use somebody else's WiFI in a remote location is great — that had been a major issue for us with several projects.”

Read Customer Story

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."

Alexander Larcombe

Associate Professor and Head of Respiratory Health, Telethon Kids Institute

Having a larger network of sensors where we have a better resolution of where air pollution is worse or better will be beneficial in allowing us to change behaviors, educate people more, or do all sorts of things to improve the health of those people

Node-S colocation

Buy pre-calibrated air quality sensors or collocate in the field

Accurate air quality monitoring starts with calibration. Clarity's rigorous Collocation and Calibration process ensures your air pollution measurements are scientifically validated and defensible.

Purchase Node-S devices pre-calibrated to generalized models by the Clarity Lab, or collocate anywhere with a reference monitor to develop custom localized calibrations — all included with Sensing-as-a-Service℠ air quality monitoring.
