DCM302B 3D compass sensor with heading Pitch and Roll output  


General Description:


DCM302B is a high precision 3D electronic compass using the 2D plane calibration algorithm, the calibration no need 3D posture tilt , just flat-situ rotation a circle to complete the calibration process.  Using USA patented technology of hard magnetic and soft magnetic calibration algorithm, make the compass eliminate the magnetic influence through calibration algorithm in the magnetic interference environment ,DCM302B integrated three-axis fluxgate sensor, in real time solver heading through the central processor, and using 3-axis accelerometer to proceed heading compensation for the wide range tilt angle, to ensure the compass still can provide high-precision heading data when the tilt angle up to ±85°.Electronic compass integrated high-precision MCU control, various output mode, standard interfaces including RS232/RS485/TTL and other interfaces, and accept other communication interface customization.

  DCM302B with small size, low power consumption, can be used for the antenna stability, vehicles, systems integration and other more fields , high shock resistance, high reliability makes the compass work properly in extremely harsh environments, and is more suitable for nowadays miniaturization military high-precision measurement integrated control system.
