Clarity

Clarity combines air sensing technology, IoT devices, and data analytics to provide governments and organizations with continuous, real-time air monitoring and air quality data. The company’s core Node-S monitoring hardware measures nitrogen dioxide and particulate matter that is 2.5 micrometers or less in diameter. Additional hardware includes the Wind Module, which measures wind speed and direction for insight into where pollution is coming from; the Ozone Module, which detects ground-level ozone, and the Black Carbon Module, which distinguishes between particulate matter from natural sources and that from fossil fuel combustion sources. Clarity’s nodes have been installed in more than 60 countries, in locations such as Los Angeles, London, Singapore, Sydney, and the Philippines.

The company offers its end-to-end platform under a “sensing-as-a-service” model, in which customers pay recurring subscription fees rather than purchasing the sensors outright. A subscription includes the air monitoring equipment, modular pole and wall mounts for easy installation, a cellular connectivity and global data plan, maintenance and equipment replacement (including hot-swaps to minimize downtime), cloud data storage and management, data dashboards, custom notifications for when measurements exceed thresholds, and a dedicated Environmental Project Manager for the duration of the subscription.

“Clean air is a fundamental human right, but you can’t fix what you can’t measure,” says David Lu, co-founder and CEO. “Our Sensing-as-a-Service model offers comprehensive, scalable, and precise air monitoring that directly contributes to cleaner air. By providing a turnkey package—hardware, software, and continuous support—without hidden costs, we make it easier for organizations to access accurate, real-time air quality data. This affordability and simplicity mean more entities can implement effective air quality measurement, enabling governments and communities to identify pollution sources and take actionable steps toward cleaner air. It's a scalable solution designed to drive real, measurable change."
