HMR2300 3-Axis Magnetometer

The Honeywell HMR2300 is a three-axis smart digital magnetometer designed to detect the strength and direction of magnetic fields. It uses three orthogonally oriented magnetoresistive sensors to measure X, Y, and Z vector components, converting outputs to 16-bit digital values via an internal delta-sigma A/D converter. An onboard EEPROM stores configuration settings for consistent operation. Data is transmitted via full-duplex RS-232 or half-duplex RS-485 at 9600 or 19,200 baud rates. Applications include attitude reference, compassing and navigation, UAVs, autonomous vehicles, traffic and anomaly detection, lab instrumentation, and security systems. A development kit with RS-232 interface, demo software, cable, AC adapter, and carrying case is available, with the demo program also offered as a free download.
