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.
This is a visualization of 64 Specks located in homes around the Pittsburgh area. Test participants placed the Speck in a room of their choice and let it record samples for up to five days at 1-minute intervals.
Use the link below to explore it yourself. Suggested exploration: set the "Show" filter to only show Specks located in the kitchen, and then slowly move the red, triangular cursor back and forth in the timeline to see changes in particles detected during typical mealtimes.
