TruePoint™ Compass Module
HMR3500
Advanced Information
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.
