The azimuth measurement of a 3D electronic compass is based on the principle of geomagnetic induction, and its installation environment must meet strict magnetic interference control requirements. To ensure measurement accuracy, the following installation specifications should be followed: 1. Magnetic Environment Requirements: The installation location should be far away from ferromagnetic materials (such as iron products, permanent magnets, etc.) and electromagnetic equipment (such as motors, transformers, etc.); the minimum distance from potential interference sources should be at least 40cm...

Calibration method Calibration prerequisites: 1) The compass accuracy does not meet the requirements; 2) If there is a fixed magnetic field interference in the compass installation environment (e.g., installed on ferrous materials), the interference source and the compass must be rotated synchronously for calibration, and their relative positions must be kept fixed during use; otherwise, recalibration is required. If the size or distance of the interference source is not fixed (e.g., a variable iron component), calibration is not possible; a safe installation distance of at least 30cm should...

1) Connect the compass correctly to the corresponding communication port and turn on the power. 2) Rotate the plane at least 360°: As shown in Figure B. Vertical Calibration Start Command Rotate horizontally at a constant speed for at least one full rotation, ensuring the time is at least 20 seconds. Values saved are only valid after 20 seconds; values saved before 20 seconds are invalid. Vertical Calibration Save Command 68 04 00 52 57 Data Field (0 bytes) No Data Field Command 1. Data frame format: (8 data bits, 1 stop bit, no parity, default rate 9600) Data Length: Length from the data length...

Protocol Item Descriptions: SOF: Start of Frame (SOF), a fixed value of 0x68; Length: Total number of bytes for all items except SOF; Load: Consists of commands or command content; Checksum: The sum of the first to third items, a single byte excluding the high-order byte.

12-axis data type output Attitude angle + 3-axis acceleration + 3-axis gyro angular velocity + 3-axis magnetic field; *The heading angle is the magnetic north heading angle, ranging from 0 to 360°.
