DCM302B MCU Control 0.8deg Magnetic Compass Sensor Inertial Measurement Unit
DCM302B MCU Control 0.8deg Magnetic Compass Sensor Inertial Measurement Unit
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. Hard magnetic and soft magnetic calibration algorithms are adopted, 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.
