Speck is a low-cost particulate monitor currently under development by the CMU CREATE Lab as a tool for citizen science and personal exposure tracking. Through community-generated advocacy maps and data visualization, this device will enable communities and individuals to better understand and quantify the quality of the air they breathe.
We arranged 144 Specks in a 12 x 12 grid to test how particles flow through the room. We tested with a vacuum cleaner, an air purifier, and candles. This video presents the test results and gives instructions on how to use the explorable. Use the link below to explore it yourself.
