The Clarity Node-S:  
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:

Matt Holmes

Air Quality Consultant and former Executive Director, Groundwork Richmond

"We couldn’t have done it with any other air quality monitoring solution. With their unique ability to operate off-grid, Clarity’s Node-S provided the ability to site our air quality monitors in the locations that mattered most to community members in Richmond. The data are reliable, real-time, and hyperlocal, and our network is now being used as a blueprint for AB 617, a landmark regulation that empowers communities to take control of air pollution."

Dr. Stig Hellebust

Lecturer in Physical Chemistry, University College Cork

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.

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."

Timothy Baker

Deputy Manager of ERG's Measurement Team

We use our reference network with collocated Node-S devices to make estimates of the interactions between the pollutants. This also helps us to make adjustments for the weather conditions like relative humidity, how damp is the air, how hot is the air.

Air Quality & Emissions Specialist, Kansanshi Mine

“There's less maintenance with Clarity’s compact Node-S device — that means less cost to actually go to that particular site. That time and cost-saving measure is critical for our business.”

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.
