| Abstract [eng] |
The article covers analysis of magnetic field sensor LSM303DLH with auxiliary components (R, C). A pair of Helmholtz coils were designed and examined. Experimental equipment able to create magnetic field of magnitude up to 1000G was produced. Research determined that residual offset in measurement of magnetic field is observed at magnitudes of external magnetic field reaching 20-50 G, depending on magnetization of the sensor. Sensitivity of the sensor is not affected by magnetization therefore offset can be eliminated during dynamic measurement of magnetic field. |
