3-Axis Compass with Algorithms
HMC6343
The Honeywell HMC6343 is a fully integrated compass module that includes
firmware for heading computation and calibration for magnetic distortions.
The module combines 3-axis magneto-resistive sensors and 3-axis MEMS
accelerometers, analog and digital support circuits, microprocessor and
algorithms required for heading computation. By combining the sensor
elements, processing electronics, and firmware into a 9.0mm by 9.0mm by
1.9mm LCC package, Honeywell offers a complete, ready to use tilt-
compensated electronic compass. This provides design engineers with the
simplest solution to integrate high volume, cost effective compasses into
binoculars, cameras, night vision optics, laser ranger finders, antenna
positioning, and other industrial compassing applications.
The HMC6343 utilizes Honeywell’s Anisotropic Magnetoresistive (AMR) technology that provides advantages over other
magnetic sensor technologies. The sensors feature precision sensitivity and linearity, solid-state construction with very
low cross-axis sensitivity designed to measure both direction and magnitude of Earth’s magnetic fields. Honeywell’s
Magnetic Sensors are among the most sensitive and reliable low-field sensors in the industry.
Honeywell continues to maintain product excellence and performance by introducing innovative solid-state magnetic
sensor solutions. Honeywell’s magnetic sensor solutions provide real solutions you can count on.
