downloadhcm385b 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.
