HCM385B 3D Digital Compass Sensor 30mA DC5V For Satellite Antenna Searching
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.
