TruePoint™ Compass Module

HMR3500

The HMR3500 TruePoint™ compass module is a 3-axis

digital compass solution with a customizable coordinate

system for mounting in any desired orientation. Three

Anisotropic Magneto-Resistive sensors and three MEMs

accelerometers are combined to provide compass heading

as well as pitch and roll angles.

The HMR3500 has provisions for hard and soft-iron

correction algorithms to handle magnetic distortion effects.

In addition a World Magnetic Model feature is provided to

automatically add declination angle corrections for

reference to true north (geographic north).

Honeywell provides product excellence and performance by introducing innovative solid-state magnetic sensor solutions.

These are highly reliable, top performance products that are delivered when promised. Honeywell’s magnetic sensor

products provide real solutions you can count on.
