Flexible Add-On Modules to meet your air quality measurement needs

Clarity's modular accessory ecosystem unlocks flexibility for air quality monitoring networks. With modules that attach in seconds, it's simple to upgrade your air quality monitoring network over time. Expand capabilities by mixing and matching accessory modules like Wind Module, Ozone Module, Black Carbon Module, and more.

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:

Eddie Ahn

Executive Director, Brightline Defense

"Clarity was our first-choice air quality monitoring provider for several reasons. We enjoyed working with the Clarity team - they are highly knowledgeable and always responsive. The Node-S devices themselves are also incredibly resilient, which was especially important for us when deploying the monitors in emergency conditions during the wildfire events this past year."

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."

Begaim Alipova

Head of Atmospheric Pollution Observation Division, Kyrgyzhydromet

"In 2020, we installed 50 sensors in the city of Bishkek. Since the Clarity Node-S sensors installed in Bishkek are small, we installed them all over the city. We placed some of them near roads, some in residential areas, and some in social facilities. Thanks to the Global SIM Card which is incorporated in the sensors, we get the data directly to our system which allows us to visualize the data. The data is ready for analysis.”

Alexander Larcombe

Associate Professor and Program 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

Dr. Ian Longley

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."

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.
