See the spatial Wifi signal strength in your home! See 3D magnetic field lines around a magnet!
Note: your device needs to support ARCore (https://developers.google.com/ar/discover/supported-devices)
This AR app visualizes sensor data from your phone (e.g., magnetic strength, Wifi signal strength, etc) and projects+visualizes them in 3D space with AR.
