How to create your own Sensor

Steps for creating your own sensors

The Qt Sensors module provides access to sensor hardware via QML and C++ interfaces.

The API is supported on Android, iOS, and Windows (MSVC).

Creating your own sensor using C++ API

Using a Qt module’s C++ API requires linking against the module library, either directly or through other dependencies.

Creating a sensor

To create your own sensor you can use the following steps:

• Create your own MySensor and MySensorReading classes

  class MyReadingPrivate():
  class MyReading(QSensorReading):
  
      Q_OBJECT
      Q_PROPERTY(qreal myprop READ myprop)
      DECLARE_READING(MyReading)
  # public
      myprop = qreal()
      def setMyprop(myprop):
  
  class MySensor(QSensor):
  
      Q_OBJECT
  # public
      MySensor = explicit(QObject parent = 0)
      reading = MyReading()
      * = char()
  

• Create a MySensorBackend by inheriting from QSensorBackend

• Create MySensorBackendFactory factory class for instantiating that backend by inheriting a class QSensorBackendFactory

• Register the backend factory by calling registerBackend (“MySensorType”, “MySensorId”, &myfactory)

• Instantiate the new MySensor and start using it

As an another option the sensors are put into a Creating a sensor plugin that you can use on demand.
