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.
