Overview

1. The module integrates high-precision gyroscopes, accelerometers, and geomagnetic field sensors. It uses high-performance microprocessors and advanced dynamic calculation and Kalman dynamic filtering algorithms to quickly solve the current real-time motion posture of the module. It has It has the advantages of wide measurement range, excellent noise immunity, no hysteresis, and stable temperature characteristics.

2. The use of advanced digital filtering technology can effectively reduce measurement noise and improve measurement accuracy.

3. The product integrates an attitude solver and cooperates with the dynamic Kalman filter algorithm to accurately output the current attitude of the module in a dynamic environment. The attitude measurement accuracy is statically 0.001°, the stability is extremely high, and the performance is even better than some professional ones. Inclinometer.

4. The Z-axis heading angle is added to the geomagnetic sensor filter fusion, which solves the cumulative error caused by the drift of the gyroscope integral in the 6-axis algorithm, and can output heading angle data stably for a long time. (Note: Due to magnetic field detection, calibration is required before use, and when used, it needs to be at least 20cm away from magnetic interference areas, electronic equipment, magnets, speakers and other hard magnetic objects.)

5. The product has its own voltage stabilization circuit, working voltage is 5~36V, and is easy to connect.

6. Military-grade magnetic field chip, automatically recovers from magnetic field interference.

7. P67 level protection, aluminum shell, strong resistance to external electromagnetic interference, stable performance, and can adapt to long-term work in harsh industrial environments.
