Air is vital for people. Yet its quality leaves a lot to be desired in many places. With innovative environmental sensory networks, inventors at Breeze want to fight bad air. To this end, they have developed measuring devices that are much smaller and less expensive than the solutions developed so far. Positioned in different places in the city, these devices provide detailed information about the levels of pollution in the air. The data obtained are collected centrally in a Cloud and evaluated. Thanks to this innovation, problems such as traffic jams can be recognised at an early stage and countermeasures taken. Breeze automatically makes suggestions to improve the quality of the air.
