Smart Trolley
The “Smart Trolley” by Philipp Pfeiffer is a combination of a Seestadt-trolley and a portable sensor device for measuring air quality, especially the fine dust content of the air. The sensor device is mounted on the trolley, which can be used by people in their daily lives, for example for shopping. The device measures the fine dust concentration, temperature, humidity and the GPS position of the trolley. Users receive feedback on the fine dust concentration in the air through light and sound and are warned in the event of heavy fine dust pollution.
