• Ensures stable data output, low noise level, and increased measurement accuracy

The Witmotion WT901C-485 MPU9250 High-Precision 9-Axis Gyro, Accelerometer, Magnetometer & Digital Compass is a scientific device used to measure 3-axis angle, angular velocity, acceleration, and magnetic field. It integrates a high-precision gyroscope, accelerometer, and geomagnetic field sensor, along with a high-performance microprocessor. The sensor also utilizes advanced dynamics fusion and Kalman dynamic filtering algorithms to quickly analyze the module’s real-time motion posture.

Thanks to WitMotion’s advanced digital filtering technology, this sensor effectively reduces measurement noise and improves measurement accuracy. It features an in-built posture solver and dynamic Kalman filter algorithm, allowing it to accurately output the current posture of the product in a dynamic environment. The measurement accuracy of the X and Y axis can reach 0.05, with extremely high stability.

Designed for optimal data accuracy and stability, the WitMotion WT901C-485 MPU9250 sensor surpasses traditional accelerometer sensors with its patented zero-bias automatic detection calibration algorithm and R&D dynamic fusion algorithm.
