Digital Compass Solution
HMR3400
The Honeywell HMR3400 is a digital compass solution designed for use in navigation and precision pointing applications.
Honeywell’s magnetoresistive sensor technology is coupled with a MEMS accelerometer to provide a miniature, reliable
tilt-compensated electronic compass. Using a common set of commands from the legacy HMR3300 digital compass
solution, the HMR3400 is designed to be easily integrated into host systems with a regulated 5 volt supply and a UART
serial data interface.
The HMR3400 includes a MEMS accelerometer for a horizontal three-axis, tilt
compensated precision compass for performance up to a ±60° tilt range.
Honeywell continues to maintain 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.
