# Clarity

> Clarity Movement Co. provides complete, end-to-end air quality monitoring through its Sensing-as-a-Service℠ model — combining solar-powered air monitoring hardware, cloud-based software, and expert support in one subscription. Clarity's systems are trusted by governments, businesses, and communities in 85+ countries and 220+ cities, with 9,000+ Node-S sensor deployments and 400M+ air quality measurements collected.

Key things to know:

- Sensing-as-a-Service℠ bundles hardware, software, connectivity, calibration, and support into a single subscription with no hidden costs.
- The flagship Clarity Node-S is a solar-powered, cellular-connected outdoor sensor measuring PM2.5 and NO2, and is the only solar-powered air sensor with UK MCERTS certification.
- The Node-S serves as a modular platform for Add-On Modules: Dust (PM10), Wind & Met, Black Carbon, FEM Ozone (EPA-approved), and Multi-Gas (CO, O3, NO2, NO, NOx).
- Data is delivered in real time via the Clarity Dashboard, a REST API, and OpenMap, a public-facing air quality data platform.
- Notable deployments include Breathe London (400+ sensors), Chicago Air Sensor Network (200+ sensors), LAUSD Know Your Air Network (200+ sensors), Yerevan (170+ sensors), and Perth's RAC Air Health Monitor (200+ sensors).
