HM55B Compass Module

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. Data Sheet Quick Facts Catalog Number: 21121 Brand: Parallax Brand's Part Number: 29123
