FNN-3400 Three-dimensional Electronic Compass
1.Profile
The accuracy of FNN-3400 built three-axis electronic compass and three-axis magnetic field sensor tilt sensor. Azimuth compass output is the angle between the horizontal plane of the projection axis north and magnetic north line on the ground projection, having a triaxial acceleration compensation due, in flat, Celi, an inverted attitude can measure magnetic north position, and can be widely used in mobile phone base station antenna detection, toys, teaching presentation equipment, low-cost satellite communications equipment, networking and testing needs.
FNN-3400 electronic compass magnetic interference can be hard or soft magnetic compensation, while having zero azimuth correction. Products with packaging and non-packaging of two types, operating temperature range: -20 ℃ to + 70 ℃.
