With extremely low magnetic field sensitivity of less than 70 µGauss, a less than 7 nano-Tesla capability, and a user configurable command set, the HMR2300 solves a variety of problems in custom applications. Honeywell’s 3-Axis smart digital magnetometer detects the strength and direction of the external magnetic field and interfaces with computer or controller digital ports. Three independent magnetic sensors are oriented orthogonally to sense the X, Y and Z-Axis magnitudes of the magnetic field. The bridge outputs are then converted to a 16-bit digital value using an internal A to D converter.
