FNN-3200 Plane Electronic Compass
1 .Product Features
（1）Through two-axis magnetoresistive sensor measures plane Earth's magnetic field, and translates the measurements into heading information.
（2）High-speed and high-precision A / D conversion. The accuracy of magnetic field measurement is 100μGuass.
（3）Embedded microprocessors calculate the angle between sensor and Magnetic North.
（4）Operating temperature is -40℃to+85℃. Storage temperature is -55℃to+100℃.
