Quick Overview

Sensitive to microtesla (μT) variations in magnetic field strength, the Compass Module Hitachi HM55B simplifies direction by resolving magnetic field measurements into 2 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", 6-pin DIP package.
Compatible with most microcontrollers including BASIC Stamp, Javelin Stamp, SX and Propeller.

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 most microcontrollers (like Arduino) and all the 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.

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.
