HMC1051为Honeywell生产的双轴磁传感器，可以用来做指南针，电子罗盘等定位系统。

当接上低噪声放大器和12到16-bit（位）模数转换器（A/D）时，使用HMC105X系列传感器可进行极高精度的测量-Production for the Honeywell HMC1051 two-axis magnetic sensor can be used to make the compass, electronic compass, GPS. When connected to the low noise amplifier and 12 到 16-bit (bit) ADC (A/D), the use of HMC105X series sensors can be extremely high precision measurement
