Portable air quality tracker Atmotube aims to be the Waze for air quality tracking in your city. The device is a tiny tube that you can carry around in your pocket or put on a key chain to monitor the air in your environment.

Atmotube links to a smartphone app that tells you if the air you are breathing is toxic. It measures a number of volatile organic compounds (VOCs), carbon monoxide, and even cleaning agents or allergens that might affect your lungs.
