Qt Sensors - Grue Sensor Example
The Qt Sensors - Grue sensor example demonstrates all the steps from creating a new sensor to using it.
The sensor definition is placed in a library where client apps can access it. The actual implementation lives in a plugin.
The sensor can now be used by a C++ application, even if the application does not have access to the definition.
To make the sensor available to a QML application an import must be created.
