 Compass Module
Brujula de estado solido.
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 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 BASIC Stamp, Javelin Stamp, and SX microcontrollers.
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.
