Click here for high res picture ...


The Parallax Compass is a dual-axis magnetic field sensor built around the Hitachi HM55B. Parallax makes this compass accessible by providing their surface-mount sensor chip with a 3V onboard voltage regulator and resistor protection in a 0.3 wide 6-pin DIP module. The HM55B is compatible with the BASIC Stamps 5V supply and signal levels. Compass date is read using a simple synchronous serial interface (the BASIC Stamps SHIFTIN and SHIFTOUT commands).

Features:
  • Sensitive to microtesla (T) variations in magnetic field strength.
  • Simplifies direction by resolving magnetic field measurements into two components axes.
  • 8-bit angular resolution +/- 1 brad 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.

Application Ideas:
  • Mobile and walking robot direction sensor
  • Handheld electronic compass
  • Weathervane indicator for remote weather stations
  • Audible compass for the vision impaired.
  • Automotive electronic compass.
