Smart Digital Magnetometer
HMR2300
The Honeywell HMR2300 is a three-axis smart digital magnetometer to
detect the strength and direction of an incident magnetic field. The three of
Honeywell’s magneto-resistive sensors are oriented in orthogonal directions
to measure the X, Y and Z vector components of a magnetic field. These
sensor outputs are converted to 16-bit digital values using an internal delta-
sigma A/D converter. An onboard EEPROM stores the magnetometer’s
configuration for consistent operation. The data output is serial full-duplex
RS-232 or half-duplex RS-485 with 9600 or 19,200 data rates.
Applications include: Attitude Reference, Compassing & Navigation,
Traffic
and
Vehicle
Detection,
Instrumentation and Security Systems.
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.

    ... HMR2300 receive (RD) data line, and the other is from the HMR2300 TD to the PC RD data line. When a logic one is sent, either the line will drive to about +6 Volts referenced to ground. For a logic zero, the line will drive to about –6 Volts below ground. Since the signals are transmitted and dependent on an absolute voltage level, this limits the distance of transmission due to line noise and signal to about 60 feet ...

    ... HMR2300 DATA FORMATS The HMR2300 transmits each X, Y, and Z axis as a 16-bit value. The output data format can be either 16-bit signed binary (sign plus 15 bits binary coded decimal (BCD) ASCII characters. The command *ddA will select the ASCII format and *ddB will select the binary format. ...

    ... To turn off the internal switching, enter the command *ddTF or *ddT. In this state the sensors are either in a Set or Reset mode. If the HMR2300 is exposed to a large magnetic field (>10 gauss), then another set pulse is required to maximize output sensitivity. ...

    ... Table for each sample rate. The default rate of 20 sps has a bandwidth of 17Hz. The digital filter inside the HMR2300 is the combination of a comb filter and a low pass filter. This provides a linear phase response with a transfer function that has zeros in it. ...

    ... Computer floppy disks (diskettes) store data with field strengths of approximately 10 gauss. This means that the HMR2300 is many times more sensitive than common floppy disks. Please treat the magnetometer with at least the same caution as your diskettes by avoiding motors, CRT video monitors, and magnets. Even though the loss of performance is recoverable, these magnetic sources will interfere with measurements ...
