Main characteristics：Main features: SEC345/SEC340 is a high-precision three-dimensional electronic compass developed by Huilian, which adopts patented three-dimensional compensation technology, so that accurate heading data can still be provided under the inclination angle of+40.
Product Introduction
SEC345/SEC340 is a cost-effective 3D electronic compass developed by Huilian, which uses patented 3D compensation technology to provide accurate heading data even at a tilt angle of ± 40 °.
SEC345/SEC340 has a small size and low power consumption, making it more suitable for volume sensitive measurement systems. It has been widely used in many fields such as antenna stability, vehicle navigation, and attitude reference.
