Abstract

According to requirement of weak magnetic field detection

Lab VIEW virtual instrument technology developed three axis of weak magnetic field detection system

using 3D Mag IC（ PNI12927） chip to drive the three axis magnetic sensor

configuration parameters and communication control on sensing device are carried out by STC12LE2052 AD MCU

and multi-function visualization system software is compiled based on Lab VIEW. By calibrating the sensitivity and linearity of the detection system

the systematic error of which is pre-compensated by means of software

real-time measurement of magnetic field at the level of 15 n T is realized. Ceomagnetic field measurement results verify the feasibility of the method.
