Outdoor air quality monitoring
About Aeroqual

Leader in Air Quality Monitoring

Aeroqual’s integrated monitoring and software systems make it simple and easy to measure the air.

Air is precious

The average person fills their lungs 20,000 times a day. Every breath brings in life-giving oxygen and carries carbon dioxide away.

As COVID-19 has demonstrated, we are incredibly vulnerable when we breathe. Nine out of ten people breathe air deemed unsafe. Every year 4.2 million people die from air pollution. Even as air quality improves for many people, scientists are lowering their estimates for what constitutes an acceptable risk. Air quality is not uniform; in the cleanest city people are exposed to highly localised pollution sources that mostly go undetected. Little surprise that air quality has become one of the defining issues of our time.

Environmental, health and safety professionals are the people who protect us from the threat of bad air. At home, in the workplace and across our cities, these professionals are making decisions that affect the lives of 8 billion people. They do an incredibly important job, and they should be celebrated.

Unfortunately, the tools and processes those professionals use to make decisions are outdated, inefficient and unconnected. Their time is wasted collecting, collating and processing data – precious time that should be spent interpreting and acting upon what the data is saying.

Aeroqual is on a mission to change that. We’ve built a global air quality monitoring platform that takes the hassle out of air quality measurement and analysis, a toolset that frees our customers up to make the decisions that matter.

Our technology

Back in 2001, we pioneered the use of sensors for monitoring the quality of ambient air. The industry was not ready for it then, but we saw the potential for low-cost lightweight sensors to complement the regulatory compliance monitoring network.

Today we are the leading air quality monitoring platform built on integrated instrumentation and software. The platform is used by environmental, health and safety professionals to keep workers and communities safe. With active users in more than 100 countries, we’re processing over 6 million datapoints every day.

Customers select the instrumentation that best suits their purpose, we deliver it to them, and they connect it up to our cloud-based monitoring platform. Data is securely accessible to them and their stakeholders anywhere and anytime, on whatever device they are using. The data is used to improve the quality of the experience for users across the network, driving new insights into diverse urban and industrial airsheds.

We have gained mastery of the technology stack all the way from fabrication of sensors to design and development of instrumentation to deployment of advanced network algorithms.

The company was formed to commercialize novel gas sensitive semiconductor technology which found immediate application in the detection of ozone. The sensors measure ozone accurately and precisely down to parts per billion, costing a fraction of ozone instrumentation based on UV absorption. We also make sensors to measure volatile organic compounds and continue to design and develop gas sensitive semiconductor technology within our R&D program.

Deep knowledge of sensor design and fabrication gives us an edge. We’ve extended our understanding of sensors to electrochemical sensors for measuring a range of gases, and optical light scattering sensors for measuring the size and mass of particulate matter. This allows us to select the best in class sensors from around the world, working closely with other technology leaders to push the limits of what the sensors can do.

All sensors experience drift and various failure modes in the field. Our team have designed numerous ways to deal with this challenge. Our patented Automatic Baseline Correction allows us to physically remove interferences on instrument. Other algorithms are deployed on the instrument to control for humidity and temperature differentials.

We coined the term Near Reference to denote a category of sensor-based instrumentation that could be operated in such a way that allowed it to be directly correlated back to standard reference materials.

Today our software development capabilities are a match for our sensor and instrumentation experience.

Our software stack leverages scalable and secure AWS infrastructure and Internet of Things pipeline. Cloud based computing allows us to develop faster and better and gives customers access to the best technology at the lowest possible cost, without the hassle of maintaining their own servers or applications.

Our point of difference in software comes through tight integration of cloud software with instrument control systems. By surfacing deep sensor diagnostic information, we can maximize data quality for customers in a way that minimizes their total cost of ownership – which has long been the Achilles heel of air quality monitoring systems.

More recently we are developing advanced software tools that automate the management and maintenance of air quality sensor networks.

For example, MOMA is a proprietary technique that uses a network proxy to make informed decisions about a sensor’s state at a given point in time. Using MOMA we know if a sensor is ‘telling the truth’ about air quality in that precise location or if drift or a failure state has led to the unexpected datapoint.

With your support we will continue to pioneer new technology in the quest for cleaner air.
