## 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.

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

This property was introduced in QtSensors 5.1.

## 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. Returns true if the sensor was stopped, false otherwise.

Please see QSensor::stop() for information.
