摘要
介绍了磁阻传感器的实验原理,用计算机origin软件对实验数据进行曲线拟合,拟合结果与传统最小二乘法处理数据相吻合。计算了霍尔灵敏度和西安市区地磁场的大小,误差较小。
The principle of magnetoresistance sensor experimental is introduced.The data measured in the ex-periment are carried out curve fitting by the origin software. The experiment result shows an excellent accord-ance with the result of data processing by traditional least square method,hall element sensitivity and Xi’ an urban earth-magnetic are calculated,it found that the error is smaller.
