The HM55B Compass Module is a dual axis field sensor that works by reading the earth’s magnetic field and determine the direction.


Description [Hide]

This dual-axis magnetic field sensor is built around the Hitachi HM55B IC. Parallax has made this compass IC accessible by providing Hitachi’s surface mount sensor chip with a 3 V onboard voltage regulator and resistor protection, all in a 0.3” wide 6-pin DIP module.

The Hitachi HM55B Compass Module is compatible with the BASIC Stamp microcontroller’s 5 V supply and signal levels. Acquiring measurements from the module is made easy with a synchronous serial interface, and even easier with the BASIC Stamp 2 commands SHIFTIN and SHIFTOUT.

Features:

  • Sensitive to microtesla (µT) variations in magnetic field strength.
  • Simplifies direction by resolving magnetic field measurements into two components axes.
  • 6-bit (64-direction) resolution after calibration.
  • Only 30 to 40 ms between start measurement and data-ready with simple synchronous serial interface.
  • Built-in resistor protection for data pins eliminates bus conflict risks.
  • Compact and breadboard-friendly 0.3 inch, 6-pin DIP package.
  • Compatible with all microcontrollers.
