Flow: the pocket sensor that measures exposure to pollution in real time
Designed by the French start-up Plume Labs, Flow is a connected, pocket-sized sensor that individuals can use to measure the level of air pollution they are exposed to, no matter where they are.
With its stylish design, Flow is made up of a box and a leather strap that can be attached to a rucksack or a bike. This precise sensor provides information on the concentration levels of nitrogen dioxide, fine particles, volatile organic compounds, humidity and the temperature of the ambient air. A mobile application displays the concentration levels of the different pollutants to which the user has been exposed in the course of the day.
