The available description identifies a device for attendance tracking. It does not specify sensors, connectivity, or components.
I found no public prototype page or accessible repository. This case adds no implementation, testing, or performance claims.
The portfolio records a second prize in the ETSIIT challenge. This summary keeps that detail and invents no metrics or team attribution.
I found no public prototype page. For a conversation about the project described in this portfolio, email me@raul-alvarez.es.
It was a student challenge; public artifacts depend on university archives.
No repo linked here; emphasis is learning and competition outcome.
