Main characteristics：Main features: SEC385/SEC380 is a high-precision three-dimensional electronic compass. The product adopts the hard iron and soft iron calibration algorithm of American patent technology, so that it can still provide high-precision heading information when the inclination angle reaches 80.
Product Introduction
SEC385/SEC380 is a high-precision 3D electronic compass that provides high-precision heading information within a 360 ° roll and+/-90 ° full tilt range.
SEC385/SEC380 is equipped with hard magnetic, soft magnetic, and tilt compensation, and outputs high-precision measurement values after compass calibration. Advanced compensation algorithms enable products to accurately output heading information even in the presence of magnetic interference.
SEC385/SEC380 integrates a three-axis flux gate magnetic sensor, which calculates heading in real-time through a central processor. The characteristics of small size, low power consumption, and rich interfaces make it widely used in many fields such as antenna stability, vehicle navigation, and artificial rainfall.
