  The Yamaha YAS530 magnetometers is a line of 3-axis magnetometers

14
  first introduced by Yamaha in 2009 with the YAS530. They are successors

15
  of Yamaha's first magnetometer YAS529. Over the years this magnetometer

16
  has been miniaturized and appeared in a number of different variants.
