SUCH electronic compass sensor is a compact and precise navigation tool that uses a two-dimensional plane calibration method, allowing easy setup with just one flat rotation. E compass sensor integrates a three-axis magnetic sensor and accelerometer to provide reliable heading data with tilt compensation up to ±85°, ensuring accuracy even in challenging conditions. With 0.8° azimuth accuracy, 0.2° inclination accuracy, IP67 protection, and a wide -40°C to +85°C operating range, it is well-suited for marine navigation, underwater robots, GPS-integrated systems, robotics, infrared imaging devices, and antenna control.
It’s a 2D/3D magnetometer module with onboard processing that reports heading relative to Earth’s magnetic field (magnetic north). Many units also include accelerometers/gyros for tilt compensation and filtering.
A proper calibration solves both by fitting an ellipsoid and computing offsets/scales.
After moving the sensor, changing payload/cabling near it, structural changes, or if you see persistent bias/jumps. Mobile robots with swappable payloads may need per-configuration calibration.
