This compass module has been specifically designed for use in robots as
an aid to navigation. The compass uses
two Philips KMZ51 magnetic field sensors, which are sensitive enough to
detect the Earth's magnetic field. The two sensors are mounted at right
angles to each other; the CMPS03 module uses this information to compute
the direction of the horizontal component of the Earth's magnetic field
to within 0.1 degree with an accuracy of 3-4 degrees.
The CMPS03 outputs a unique number to represent the direction the robot
is facing. Interfaces easily with the Mark III or your own robot design.
Comes completely assembled - this is not a kit.
