Web/API/Sensor

The Sensor interface of the the Sensor APIs is the base class for all the other sensor interfaces. This interface cannot be used directly. Instead it provides properties, event handlers, and methods accessed by interfaces that inherit from it.

If a feature policy blocks use of a feature it is because your code is inconsistent with the policies set on your server. This is not something that would ever be shown to a user. See Feature-Policy for implementation instructions.
