This Compass Module made exclusively by Parallax is a dual-axis magnetic field sensor 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 all Parallax microcontrollers (including 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 most microcontrollers including BASIC Stamp, Javelin Stamp, SX, and Propeller.
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.
