Reliable Air Quality Monitoring, Anywhere

Clarity Movement Co. is an environmental technology company providing a complete Sensing-as-a-Service solution for ambient air quality monitoring. Their offering includes solar-powered Node-S air quality sensors, a cloud-based data platform, and expert support—empowering governments, businesses, schools, and communities to measure air pollution reliably and affordably.

Clarity’s Sensing-as-a-Service℠ bundles sensors, software, data connectivity, and support into a single subscription. You deploy Node-S air pollution sensors, and Clarity handles data transmission, calibration, and ongoing maintenance. There are no hidden costs—just fast, simple setup and real-time data via the Clarity Cloud.

Clarity sensors are calibrated using remote and local methods to ensure decision-grade accuracy. Their patented Remote Calibration system aligns low-cost sensor data with regulatory standards, and ongoing updates (e.g. wildfire calibration models) keep data accurate even in extreme conditions. Third-party evaluations show strong performance compared to reference monitors.

Clarity sensors are deployed in 85+ countries and 250+ cities, collecting billions of data points globally. Projects include Breathe London, Los Angeles Unified schools, and Bishkek, Kyrgyzstan. Clarity supports governments, NGOs, researchers, and industry.

Traditional monitors are expensive and sparse. Clarity offers dense sensor networks that are easy to deploy (solar-powered, cellular-enabled) and deliver hyperlocal data in real time. The fully integrated system removes complexity—hardware, software, and calibration come together in one seamless platform.

Clarity serves cities and regulators, communities, schools, industries, and researchers. Customers—from the Mayor of London’s office to small rural counties—use Clarity’s data to inform policy, protect public health, manage compliance, and engage the public.

The most common ambient (or outdoor) air pollutants are Particulate Matter (PM 10 and PM_2.5), Ozone (O₃), Nitrogen Dioxide (NO2), Carbon Monoxide (CO), and Sulfur Dioxide (SO2).

Particulate Matter (PM10, PM_2.5 and PM1) is a common & impactful air pollutant resulting primarily from combustion, including industrial activities, vehicles, & wildfires. Particulate matter differs greatly in its concentration and composition across the world but has a significant impact on public health in most countries. It is classified according to the size of its particles, the smaller categorization of which — PM_2.5 — accounts for much of the pollutant’s detrimental effect on human and environmental health. Although the effects of PM are well studied, it remains in excess of benchmark levels for a large majority of the world’s population, prompting the need to take action in order to achieve cleaner air. Learn more about Particulate Matter here.

Ozone or O₃, occurs both in the upper atmosphere and at the ground level. While it is a helpful substance in the upper atmosphere — forming a layer around the Earth to protect the planet’s surface from the sun’s ultraviolet rays — ozone acts as a pollutant at the ground level, causing negative effects on human and environmental health. Also known as ambient or tropospheric ozone, ground-level ozone is the primary component of the type of air pollution commonly referred to as smog. It is a colorless gas that is composed of three atoms of oxygen. Learn more about Ozone here.

Nitrogen dioxide (NO₂) is a subtype of a class of air pollutants known as nitrogen oxides (NO_x). It primarily results from fuel combustion from sources such as motor vehicles and industrial activities. Nitrogen dioxide has significant impacts on human and environmental health, most notably when it comes to respiratory and cardiovascular health. Learn more about Nitrogen Dioxide here.

Carbon Monoxide (CO) is an odorless, colorless, tasteless gas formed by the incomplete combustion of fuel. It is very dangerous as it can displace the oxygen in the human body and lead to deadly poisoning. It is produced from fuel-burning appliances. Learn more about Carbon Monoxide here.

Sulfur Dioxide (SO2) is an air pollutant composed primarily of sulfur and oxygen. It results from combustion of coal, oil or diesel. It causes harmful effects on the lungs.

Yes — Clarity’s air quality sensors are specifically designed to detect fine particulate matter (PM_2.5), which is a major component of wildfire smoke. In addition, Clarity offers modular pollutant measurement capabilities including nitrogen dioxide (NO₂), ozone (O₃), and black carbon, allowing for tailored monitoring of specific air pollution sources such as traffic, industry, or biomass burning.

Clarity provides the tools to make air quality data publicly accessible through its OpenMap air quality data platform, which enables organizations to share real-time data with communities, stakeholders, and the general public. While the data is not open-source by default, it can be transparently published and easily embedded into websites, dashboards, or public health initiatives.

Monitoring air quality empowers communities to protect public health and helps businesses reduce risk, demonstrate environmental responsibility, and ensure compliance with regulations. With real-time data, decision-makers can respond quickly to pollution events, track long-term trends, and implement evidence-based strategies that improve air quality and quality of life.

There are two types of air pollution causes: natural sources and human-caused (AKA  anthropogenic) sources.

Natural events can cause air pollution such as wind that carries dust and gases in locations with little green cover to absorb it, living beings release gases such as oxygen from plants during photosynthesis or methane from cattle but also volcanic eruptions, smoke, and ashes from wildfires.

Human-caused air pollution comes from various human activities including burning fossil fuels, agriculture, transportation, electricity, and industries. These activities result in emissions of carbon dioxide, nitrogen oxides, sulfur dioxide, volatile organic compounds, and particulate matter.

Air pollution affects nearly every area of the human body — from head to toe. It is a major environmental risk factor for a slew of diseases, from Alzheimer’s disease to lung cancer to osteoporosis, and can significantly lower lifespan and quality of life. Air pollution accounts for extensive damage to public health, while its exposure impacts everyone, its damage is not distributed equally. Children, elderly individuals, those with pre-existing conditions, and those living in low socioeconomic neighborhoods or environmental justice communities bear a disproportionate burden of its impacts — emphasizing the need to protect vulnerable populations by taking better care of our air quality.

In general, the wide-reaching damage caused by air pollution is thought to be a result of the systemic inflammation it causes. It can impact various body parts, including the eyes, brain, lungs, heart, stomach, liver, bones, and reproductive organ. Learn more about the health impact of air pollution here.
