Detailed Description

The Sensor element serves as a base type for sensors.

This element wraps the QSensor class. Please see the documentation for QSensor for details.

This element cannot be directly created. Please use one of the sub-classes instead.

Property Documentation

active : bool

This property holds a value to indicate if the sensor is active.

Please see QSensor::active for information about this property.

alwaysOn : bool

This property holds a value to indicate if the sensor should remain running when the screen is off.

Please see QSensor::alwaysOn for information about this property.

availableDataRates : list<Range>

This property holds the data rates that the sensor supports.

Please see QSensor::availableDataRates for information about this property.

axesOrientationMode : Sensor::AxesOrientationMode

This property holds the mode that affects how the screen orientation changes reading values.

Please see QSensor::axesOrientationMode for information about this property.

This property was introduced in QtSensors 5.1.

bufferSize : int

This property holds the size of the buffer.

Method Documentation

bool start()

Start retrieving values from the sensor. Returns true if the sensor was started, false otherwise.

Please see QSensor::start() for information.

bool stop()

Stop retrieving values from the sensor.

Please see QSensor::stop() for information.
