Phyphox-Bibliothek
Zuerst muss man den PhyphoxBLE-Ordner, in der die Phyphox-Bibliothek gespeichert ist, herunterladen: https://github.com/phyphox/phyphox-micropython/tree/main/phyphoxBLE
Diesen Ordner muss man dann auf den ESP laden
Um Sensoren auszulesen und diese in Phyphox anzeigen zu lassen muss man nun die Bibliothek des gewünschten Sensors herunter- und auf den Mikrocontroller daraufladen
