Digital Compass Solution
HMR3000
The Honeywell HMR3000 is a digital compass module that
provides heading, pitch, and roll outputs for navigation. The
three of Honeywell’s magneto-resistive sensors are oriented in
orthogonal directions plus a fluid tilt sensor are employed to
measure the vector components of the earth’s magnetic field
and a gravitational reference. These solid-state sensors create
a strapdown compass that is both rugged and reliable. The data
output is serial full-duplex RS-232 or half-duplex RS-485 with
1200 to 19,200 data rates.
Applications include: Compassing & Navigation, Dead
Reckoning Backup to GPS Systems, Marine Navigation,
Antenna Positioning, and Land Surveying
A RS-232 development kit version is available that includes a windows compatible demo program, interface cable, AC
adapter, and carrying case.
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 solutions provide real solutions you can count on.
