SEC290 Nine-axis Attitude Electronic Compass is a product of BwSensing Technology. It is suitable for unmanned vehicles, satellite tracking, petroleum geological exploration, and other fields. The product features high precision, low cost, and strong anti-interference capability.
The BWSensing SEC290 Series 9-axis attitude electronic compass is an inertial product designed for high-precision roll, pitch, and azimuth measurements in environments with magnetic interference and dynamic motion. It integrates a 3-axis gyroscope, 3-axis accelerometer, and 3-axis magnetometer, utilizing an optimized Extended Kalman Filter algorithm to output real-time attitude information. The device is suitable for applications such as unmanned vehicles, marine surveys, underwater navigation, and mechanical control, offering features like dynamic/static measurement, hard/soft magnetic compensation, and a wide operating temperature range of -40°C to +85°C.

Avoid installing the sensor near ferromagnetic substances or strong magnetic fields (e.g., engines, motors, antennas) within 10cm to prevent irreversible accuracy degradation.
It is strongly recommended to perform magnetic calibration after installation and whenever the magnetic environment changes.
If calibrated correctly according to the manual, the azimuth accuracy will be less than 3 degrees (RMS).
The series offers RS232, RS485, and TTL interfaces depending on the specific model variant.
