... PCB or Aluminum Enclosure Options • 6-15 volt DC Unregulated Power Supply Interface General Description 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 ...

... 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 ...

... 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. ...

... The HMR2200 Smart Digital Magnetometer contains all the basic sensors and electronics to provide digital indication of magnetic field strength and direction. The HMR2300 has all three axis of magnetic sensors on the far end of the printed circuit board, away from the J1 and J2 connector interfaces. The HMR2300 uses the circuit board mounting holes or the enclosure surfaces as the reference mechanical directions ...
