▶ INTRODUCTION
DCM301B/DCM302B is a 3D electronic compass with high precision using two-dimensional plane
calibration algorithm. The calibration does not require a three-dimensional attitude tilt, and only needs to
rotate the plane in place to complete the calibration process. Using hard magnetic and soft magnetic
calibration algorithms, the compass can achieve ideal measurement results through three-dimensional
calibration in an environment with magnetic interference. This compass integrates three-axis magnetic
sensing technology, which can calculate the heading in real time through the central processing unit, and
A three-axis accelerometer is used to compensate for a wide range of tilt angles to ensure that the
compass can provide accurate heading data even at tilt angles of up to ±85°. The electronic compass
integrates high-precision MCU control, with diversified output modes. The standard interfaces include
RS232/RS485/TTL and other interfaces, and other communication interfaces can be customized.
DCM302B is small, low in power consumption, and can be used in many fields such as antenna
stability, vehicles, and system integration. Its high shock resistance and high reliability also enable the
compass to work normally in extremely harsh environments, and it is suitable for high-precision
measurement integration control system.
