How can a Hall effect sensor monitor changes in orientation relative to a magnetic field?

A change in orientation can change the component of the magnetic field detected by the sensor.

What is the limitation of using a single magnetic field reference to determine an object's attitude?

It does not uniquely determine every aspect of the object's attitude.

What does a Hall effect sensor detect as a rotating object moves in a tachometer?

Periodic changes in the magnetic field.

How can rotational speed be determined from repeated Hall sensor signals?

Count the signals over time and divide by the known number of signals per revolution.
