Collect and Share Outdoor Air Quality Data
Are you curious about the quality of air that you breathe? The World Health Organization (WHO) released a report that indicates 92% of the world's population is breathing unsafe air. WHO reported that 7 million people died in 2012 as a result of air pollution exposure and of those, an estimated 3.7 million premature deaths are attributed to ambient (outdoor) air pollution.
In most cases the air we breathe is invisible and we don't think about it until we get a cough or worse. By collecting particulate matter data, which affects more people than any other pollutant, with a high quality, reliable device, each of us is empowered to convert the invisible air we breathe to data that we can analyze and use to make decisions about how we interact with our environment.

The Safecast team has more than 5 years of experience developing environmental monitoring devices and large scale deployment. They have spent a considerable amount of time testing many particulate sensors to ensure that the sensor data will be reliable and supported by governmental agencies and environmental institutions.
It's incredible important to you as a consumer, that the data is not only accurate but is recognized as trustworthy. Safecast supports open source hardware and data. That means that anyone can build these devices and access the data as opposed to being closed and proprietary.
The Safecast Air device is designed to be a static sensor, permanently installed in a single location with fixed power and internet for the data consumption. This model measures particulate (in PM10, PM2.5 and PM1.0) and environmental calibration data (temperature and humidity).

Outdoor Air Quality and Health Fact Sheet
These facts come from the World Health Organization's fact sheet on outdoor air pollution.
- Air pollution is a major environmental risk to health. By reducing air pollution levels, countries can reduce the burden of disease from stroke, heart disease, lung cancer, and both chronic and acute respiratory diseases, including asthma.
- In 2014, 92% of the world population was living in places where the WHO air quality guidelines levels were not met.
- Ambient (outdoor air pollution) in both cities and rural areas was estimated to cause 3 million premature deaths worldwide in 2012.
- Some 88% of those premature deaths occurred in low- and middle-income countries, and the greatest number in the WHO Western Pacific and South-East Asia regions.
PM affects more people than any other pollutant. The major components of PM are sulfate, nitrates, ammonia, sodium chloride, black carbon, mineral dust and water. It consists of a complex mixture of solid and liquid particles of organic and inorganic substances suspended in the air. The most health-damaging particles are those with a diameter of 10 microns or less, (≤ PM10), which can penetrate and lodge deep inside the lungs. Chronic exposure to particles contributes to the risk of developing cardiovascular and respiratory diseases, as well as of lung cancer.
Safecast is an international non-profit organization whose goal is to create useful, accessible, and granular environmental data for public information and research.
Safecast maintains the largest open dataset of background radiation measurements ever collected - over 50 million readings to date and growing daily. Now they are adding air quality data readings to their open dataset.
Similar to the radiation data set, all of the air quality data collected is available through an open, free and public map of all submitted environmental data readings that can be accessed via browser or smartphone.
Safecast Device Users
The Safecast community spans the globe. Community members have collected radiation data on every single continent and shared it to create the largest, open, and independent radiation data set with over 50 million radiation data points. Be the very first to use Safecast's Air Quality Monitoring device in the field and be on the forefront of one of the largest air quality collection projects on the planet.
