HIGH ACCURACY 3D DIGITAL COMPASS SENSOR
2020 New Type NMEA0183 High Accuracy 3D Compass Sensor For Satellite Antenna Searching
PRODUCT DESCRIPTION
HCM380B / 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.
HCM380B / 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. HCM380B / HCM385B has been widely
used in many fields such as stable antennas, vehicles, and system integration.
