Products Desc. 

DCM250B&260B is a three-dimensional electronic compass, which adopts hard magnetic and soft magnetic calibration algorithm, so that the compass can eliminate the influence of magnetic field through the calibration algorithm even in the environment with magnetic field interference. DCM250B&260B integrates a three-axis fluxgate sensor, calculates the heading in real time through the central processing unit, and uses a three-axis accelerometer to compensate for a wide range of tilt angles to ensure that the compass can provide high accuracy even at tilt angles of up to ±85° Heading data. The electronic compass integrates high-precision MCU control, with diversified output modes. The standard interfaces include RS232 / RS485 / TTL and other interfaces, or the customization of other communication interfaces. DCM250B&260B is small in size and low in power consumption. It can be used in many fields such as antenna stability, vehicles, system integration, high shock resistance, high reliability, and the compass can work normally in extremely harsh environments, and is more suitable for today's various precisions and high measurement integrated control system.
