▶ INTRODUCTION
DCM250B/260B is a low-cost three-dimensional electronic compass,
using hard and soft magnetic calibration algorithm, so that the
compass can eliminate the influence of magnetic field through the
calibration algorithm in the environment with magnetic field
interference. The DCM250B&260B integrates a three-axis fluxgate
sensor, calculates the heading in real time through the central
processor, and uses a three-axis accelerometer to perform heading
compensation for a wide range of tilt angles, ensuring that the
compass can also provide high accuracy at tilt angles up to ±85°
Heading data. The electronic compass integrates high-precision MCU
control and diversified output methods. The standard interfaces
include RS232/RS485/TTL and other interfaces, and other
communication interfaces can be customized.
The DCM250B/260B is small size, low in power consumption, and can
be used in many fields such as stable antennas, vehicles, system
integration, etc. The high shock resistance and high reliability
also make the compass work normally in extremely harsh
environments, and is more suitable for today's Precision
measurement integrated control system.
