MYPART, AN OPEN SOURCE PORTABLE AIR PARTICLE COUNTER

One of the most harmful airborne pollutants with respect to human health is particulate matter. Air particle counters are used to determine the air quality by counting and sizing the number of particles in the air. This information is useful in determining the amount of particles inside a building or in the ambient air. It is also useful in understanding the cleanliness level in a controlled environment.

Airborne particles with a diameter of less than 10 microns pose a large risk, they can travel deeply into the respiratory system, causing a variety of cardiovascular and respiratory diseases. Combustion (e.g. burning wood; automobiles) can generate particles less than 2.5 microns in diameter. Between 2.5 and 10 microns are particles such as dust, pollen, and mold. (More information about particulate matter can be found here.)

Four members of the Hybrid Ecologies Lab at UC Berkeley, Rundong Tian, Sarah Sterman, Chris Myers, and Eric Paulos, developed “MyPart”, a device that attempts to measure air particulate matter

MyPart

MyPart’s design focuses on four goals; accuracy, size and portability, cost, and open source.

Accuracy

In the test chamber, smoke concentration was allowed to decay naturally over about 2 hours. Three prototypes of MyPart gave similar accuracy results to an expensive instrument results ($5000 MetOne HHPC-6).

Additional experiments conducted with calibration particles of known sizes and in outdoor ambient environments, and more information about the tests can be found here.
