摘要
Abstract
For requirement of detecting at some distance away a ferromagnetic object and working at low power dissipation,a double axis and micro-power magneto-resistive sensor is developp-ed based on HMC1052.The circuit of pulse for power supply is designed for reducing the power dissipation of magnetic sensor.The result of testing proves that the current fall from 4.7mA to 4.7 μA;Set/Reset circuits has been finished.The sensitivity of the magnetoresistive sensor is 1.42μV/nT,ensured through experiment and the noise is 12nT.The high performance and low power dissipa-tion of the sensor can fit for the application of long distance＇s detection and battery-powered.关键词
