What Is AirCasting and Why Do I Care

Air pollution is a staggering worldwide problem. Sources estimate that poor air quality costs the United States alone over $78 billion dollars annually. The negative impacts of air pollution rank it among the most serious and widespread human health hazards in the world. Breathing dirty air causes chronic illnesses such as asthma and bronchitis and contributes to terminal illnesses such as cancer and heart disease. Unfortunately, despite the very real impacts air pollution has on our every day lives, it often goes unnoticed because it is largely invisible. In addition, because government-run air quality monitoring networks are sparse, publicly available air quality measurements don’t translate into an accurate assessment of personal exposure. The answer? Low-cost, portable air quality instruments. This is where YOU, AirCasting, and the AirBeam come in.

Taking Matter(s) Into Our Own Hands

AirCasting is an open-source platform comprised of wearable devices and digital media that enables AirCasters (that’s you!) to independently and accurately collect and broadcast air quality data. But at its core, AirCasting is a DIY air monitoring movement that uses information about local environments to inform, educate, share, and ultimately improve health in communities around the world.

AirCasting: How It Works

The AirCasting platform was built as an open-source, end-to-end solution for collecting, displaying, and sharing health and environmental data using your smartphone. The platform consists of wearable sensors that detect changes in your environment and physiology, including a palm-sized air quality monitor called the AirBeam2, the AirCasting Android app, the AirCasting crowdmapping website, and wearable LED accessories. By documenting and leveraging health and environmental data to inform personal decision-making and public policy, the AirCasting platform empowers citizen scientists and changemakers like you and me to take matters into our own hands.

What Is The AirBeam and How Does it Work

Currently, the AirCasting platform connects a series of wearable devices to a network, notably an Arduino-powered, portable, palm-sized air quality monitor called the AirBeam2. AirBeam2 measures fine particulate matter, also known as PM2.5. You may be saying to yourself, “Why is this important?” Answer: The US Environmental Protection Agency monitors and regulates six criteria air pollutants, one of which is PM2.5, and the EPA’s measurements indicate that PM2.5 levels pose a substantial health risk in cities across the country.

The AirBeam

PM2.5, describes the size of the particles measured, particles smaller than 2.5 microns in diameter. These tiny particles, 30 of which could fit across the width of a human hair, are a huge problem all around the world. Sources of PM2.5 include diesel cars and trucks, coal burning power plants, forest fires, and construction activities. Because PM2.5 particles are so small, they are able to penetrate deep into our lungs and even pass into our bloodstream causing both short-term affects, like asthma attacks, and long-term affects, like cancer and heart disease.

The AirBeam2 uses a light scattering method to measure PM2.5. Air is drawn through a sensing chamber wherein light from a laser scatters off particles in the airstream. This light scatter is registered by a detector and converted into a measurement that estimates the number of particles in the air. Via WiFi or cellular, these measurements are transmitted to the AirCasting server every minute where they are mapped and graphed. Via Bluetooth, these measurements are communicated every second to the AirCasting Android app, which maps and graphs the data in real time on your smartphone before sending it on the the AirCasting website.

AirCasting Android App

Wait, There’s More . . .

Staring at a screen can be a drag (and may lead to being run over while walking or biking!) so we developed the LiteBeam to communicate the AirBeam2 measurements using LEDs. The LiteBeam uses a IOIO microcontroller connected to the AirCasting app over Bluetooth to illuminate LEDs in response to the sensor measurements received by the AirCasting app: green for low intensity, then yellow, then orange, and red for high intensity.

Who Uses AirCasting

To date, the AirCasting app has been downloaded over 20,000 times and there are thousands of active changemakers currently using the AirCasting platform, including community-based organizations, schools, research institutions, and citizen scientists interested in health and environmental monitoring, electrical & mechanical engineering, design, rapid prototyping, and open source code.

What's Next For Aircasting

AirCasting is more than just a product, it’s a movement and we need you! We are seeking . . .

Instrument Makers interested in developing AirCasting compatible sensor packages for new environmental and physiological sensing applications. It’s simple to connect your own custom-designed sensor package to the AirCasting app to display and record measurements in real-time.

Educators & Community Leaders interested in applying science, technology, engineering, art & design, and mathematics to address urgent environmental issues where they live. Schools and community organizations are the vital link between our technology and its application to real world problems.

Open Source Coders to push the limits of what’s possible with the AirCasting platform – gamify, add social networking layers, improve instrument performance & communications – the possibilities are truly endless. Because sharing information freely empowers communities to develop their own best solutions, everything we do, from hardware to software, is open source.

Citizen Scientists from around the world to take measurements, contribute to the crowdmap, and make change! We live in a world where expert knowledge is no longer the exclusive province of experts, where citizens, armed with affordable and accessible instruments, can make unprecedented contributions to scientific understanding.

Why Is AirCasting Different


The AirCasting platform is managed by HabitatMap, a 501(c)(3) dedicated to raising awareness about the impact the environment has on human health, and not by a private company. Meaning that funds raised in excess of the cost to produce and ship the AirBeams and provide customer service goes directly to improving the AirCasting platform software.

Tested & Verified
Our work with schools and community based organizations emphasizes the “science” behind citizen science. Our experience has shown that when AirCasters know how a measurement is made they feel empowered: they are better able to share and explain their findings to others and use that information to critically evaluate the quality of the data being collected. This approach also builds trust between communities, regulators, and policy makers. Plus, science is fun! For more on the science behind the AirBeam2 visit our blog, TakingSpace, where we’ve posted information regarding the technical specifications, operation, and performance of the AirBeam2.

Open Source
Everything we do is open source because we believe in the power of community to make change. The AirCasting app and website code is on GitHub as is the AirBeam2 firmware and the electronic schematics for the AirBeam2. The STL files for 3D printing the AirBeam & LiteBeam enclosures can be downloaded from Shapeways. Now the only question is… what will you build?
