1.   CMPSO3

     


 This great little compass was designed by Robot Electronics specifically for use in robots to aid navigation. The compass uses the Philips KMZ51 magnetic field sensor, which is sensitive enough to detect the Earth's magnetic field. Two of them mounted at right angles to each other can be used to compute the direction of the horizontal component of the Earth's magnetic field.

  2.  Vector 2Xe

 Vector 2Xe는 전세계 최고 성능을 자랑하는 미국 국방성 지원 벤처업체 PNI Corporation사의 2축 전자 콤패스입니다.


 CompassPoint V2Xe is a pre-programmed 2-axis digital compass module with an onboard microprocessor for true plug-and-play compass magnetic sensor and magnetometer functionality.

CompassPoint V2Xe allows designers to bypass the time and expense required to build a 2-axis digital compass from scratch. It offers high resolution and azimuth accuracy, temperature, stabilization, and an all-digital interface. The V2Xe's non-volatile memory retains accurate calibration even when it's powered down.

PNI's magneto-inductive sensor technology provides low power consumption, high signal/noise immunity under all conditions, and software-configurable resolution and field measurement range, CompassPoint V2Xe is the perfect solution for adding compass heading functionality to virtually any application — from hobbyist projects and consumer electronics prototypes to high-performance solid-state navigation sensor and magnetometer equipment.
