We are in the 5th week, we have now a first sketch of an application interface, in order to manage the loggers and get the data.
We learned how to use Altium, a printed circuit CAD software . Tobia designed an antenna, and built it on a PCB at EPFL-Ecal.lab (picture).
For the milestone, we had to make a first breadboard prototype (picture). We connected the sensor to a microcontroller, to stream the data of temperature and pressure on a computer. Then, we shown how we can load the data by NFC thank to a smartphone. We left the meeting quite early, to catch a train to G3ID (Geneva Global Goals Innovation Day), explained in a following post.
