| Abstract: | The function and use of a new type high sensetive magneto-resistance sensor is briefly introduced. The sensitivity is tested and furthmore, the main parameters of the earth-magnetic field are measured, too. The experimental results indicate that the viability and precision may be achieved by this sensor in measuring the infirm magnetic field. |
