* YMagnetometer Class: magnetometer control interface, available for instance in the Yocto-3D-V2
*
* The YSensor class is the parent class for all Yoctopuce sensor types. It can be
* used to read the current value and unit of any sensor, read the min/max
* value, configure autonomous recording frequency and access recorded data.
* It also provides a function to register a callback invoked each time the
* observed value changes, or at a predefined interval. Using this class rather
* than a specific subclass makes it possible to create generic applications
* that work with any Yoctopuce sensor, even those that do not yet exist.
* Note: The YAnButton class is the only analog input which does not inherit
* from YSensor.
