Clarity Node

General Description

The Clarity Node is a an air quality monitoring instrument designed to provide near real-time air quality data of PM2.5 (0-1000 μg/m3), nitrogen dioxide (NO2: 0-3000 ppb), carbon dioxide (CO2: 0-1000 ppm), total volatile organic compounds (VOC: 0-1000 ppm), temperature, and relative humidity. The Clarity Node pushes data to the Clarity server and authorized users can access data via a web browser on an internet-connected device.

Principle of Operation

This device incorporates a Laser Particle Counter (LPC) which uses a light scattering method to size and count particles and then convert them to a mass fraction.
