HCM385B is a high-precision 3D compass sensor, and the protection reaches IP67 level. Using advanced hard and soft iron calibration algorithms, make any tool surface with a roll angle of 360 ° can still provide high-precision heading information. With the characteristics of small size and low power consumption, it is more suitable for today's miniaturized sensitive measurement systems. The product can be ordered with a complete sealed casing or a circuit board.HCM385B integrates three-axis magnetic flux gate technology. It uses a central processing unit to calculate heading data in real time, and uses a three-axis accelerometer to compensate for a wide range of tilt angles. It is a high-performance, high-stability military-grade product. HCM380B / HCM385B has been widely used in many fields such as stable antennas, vehicles, and system integration.
