{{Introduction
|Introduction=Phyphox est une application compatible Android et iOS qui permet de visualiser les capteurs de votre téléphone et ainsi de faire un petit laboratoire de poche.

Il existe des fiches expériences sur le site officiel vous permettant par exemple de calculer la vitesse du son, mesurer la vitesse d'un ascenceur et pleins d'autres choses !

dans ce tutoriel, nous allons voir comment ajouter n'importe quel capteur à l'application grâce à un ESP32 connecté en bluetooth.
