Second, description of the product
LP3500 compass sensor used are: three-dimensional and two-dimensional angle sensor magnetoresistive sensor. Among them, the magnetoresistive sensor measuring Earth's magnetic field, inclination sensor compass attitude. Output point is the compass point north axis in the horizontal plane of projection and magnetic north line of the angle between the ground projection.
As the magnetic compass is based on principles of magnetic heading angle calculated to reduce or eliminate the interference of its output accuracy of the magnetic field is applied in the project must be addressed. Affect the precision electronic compass orientation of factors, such as the magnetic sensor installation error, inherent magnetic compass device data acquisition and conversion error (collectively referred to as electrical error), the non-existence of multi-axis orthogonal magnetic sensor error, interference caused by magnetic field Luo poor. For the installation error, electrical error, non-orthogonal error, you can improve the design, manufacture and installation of technology and other measures to eliminate or weaken its compass heading accuracy. Use of the environment caused by ferromagnetic media in magnetic field caused by magnetic interference of Compass is a compass heading accuracy of the largest and most difficult to control.
In the absence of interfering magnetic field, compass rotated in the horizontal plane, the output of the (Hx-Hy) ideal curve is a center of the circle in the coordinate origin of the perfect circle, see figure below; hard iron interference resulting from a permanent magnet or magnetic metal, such interference with the compass fixed relative position, in the compass of the output value of adding a fixed value, the compass rotated in the horizontal plane, the output of the (Hx-Hy) curve is eccentric, see chart below; soft iron interference generated in the Earth's magnetic field and near the magnetic compass of any interaction between the degree of its interference with the direction of the compass. In general, by the soft magnetic interference, the compass level rotated, the output of the (Hx-Hy) curve is the ellipse, see the figure below.
