The idea was carried out by scientists Hubert Flore, Ulrich Norbisrat and colleagues, who published studies in the IEEE widespread information process.
The team collected a prototype of four old smartphones, removed the batteries, and combined external power supplies for security. The devices were merged to a single system and placed in 3D printed situations.
The cost of replacing a phone was only 8 €. The prototype was successfully tested under water – automatically analyzed the video and changed the manual work of the divers, considering the sea inhabitants.
Such mini -dated centers can be used to collect data in cities, for example, can be used at bus stops for passenger counts or in rural areas for environmental monitoring.
The work shows: Old tools do not need to turn into garbage – they become part of a stable digital infrastructure with the right approach.
