How Clarity air pollution monitoring works

Each air quality measurement point's annual data license covers everything you need to cost-effectively measure air quality at scale, including:

Introducing Clarity Modules

Our core technology — the Clarity Node-S — has been re-imagined and re-engineered to vastly expand the capabilities of our air quality monitoring solution.

With Clarity Modules, the Node-S is now a platform for scalable air quality measurements beyond particulate matter and nitrogen dioxide — helping you derive more complete air quality insights than ever before.

Air quality data collection

Clarity’s flagship particulate matter (PM2.5) and nitrogen dioxide (NO2) monitor is self-powered, FCC/CE certified, UV-resistant, and weatherproof. A truly self-sufficient IoT air quality monitoring system with solar harvesting, internal battery, and global cellular communications, the Clarity Node-S accommodates site-specific requirements according to the customer’s 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.

Clarity air quality data in the cloud

Once the Node-S samples its first air quality measurements, the data are uploaded via 3G/4G LTE to the Clarity Cloud, where everything is processed and stored. Access pollutant data via the Clarity Dashboard and Clarity OpenMap web apps, or retrieve measurements and sensor data using Clarity’s REST API.

There are no extra costs associated with the Clarity Cloud. All cellular costs, data storage, and web app access are included in our service.

Clarity Dashboard

The Clarity Dashboard is a private air quality data visualization and management web app. Users log in with their unique account credentials to manage air quality monitors and view, plot, and download current and historical raw and calibrated data.

  • Configure, manage, and check sensor status
  • View, plot, and download raw or calibrated data
  • Assign user roles for access to sensor management and/or data analysis

Clarity OpenMap

Clarity OpenMap is an opt-in platform for customers who wish to add their air pollution measurements to our public repository of open data. Data from Clarity and government reference monitors are displayed as an easy way to share pollutant data with the public and generate awareness.

  • View, plot, and share data in an open repository
  • Embed in public websites using iFrame
  • Access seasonal data overlays
