Design studio NotAnotherOne has designed a portable air quality monitor that clips onto your bag to test local pollution levels.
Atmotube is a discreet black device made from plastic with aluminium details, that weighs less than 100 grams and can be easily attached to a bag or item of clothing so that it travels with the wearer.

Designed by San Francisco industrial design studio NotAnotherOne, it aims to make tracking the quality of the air you breathe easier.
While the user goes about their day, the device measures the quality of the air that they breathe in real time, and sends the data to the user's mobile phone via bluetooth.

If the air quality falls below a certain level, the device will send an alert to let the user know that they are being exposed to toxic air, so that they can change their route, or wear a mask to protect themselves.
Three in-built sensors measure particulate matter (PM) pollution consisting of particles in the air that measure up to one, 2.5 and 10 micrometres ? a unit of measurement that is one millionth of a metre.
Micro-particles less than 10 micrometres long that are suspended in the air can easily enter the lungs and cause potential health problems. These might include dust, pollen, soot, smoke, aerosol vapours and mould spores.

Atmotube also contains a sensor that detects the concentration of volatile organic compounds (VOCs) in the air, such as benzene or formaldehyde that are released by burning fuels including coal or natural gas, as w...
