Specification
Highlights
SINDT’s scientific name is AHRS IMU sensor. A sensor measures 3-axis angle, angular velocity, acceleration. SINDT is employed where the industrial-level measurement accuracy is required. Its strength lies in the algorithm which can calculate three-axis angle accurately.
Ground breaking bias stability, low noise level and good vibration robustness
Persued for best data accuracy and stability: WTMOTION patented zero-bias automatic detection calibration algorithm and R&D dynamic fusion algorithm outperforms traditional accelerometer sensor

Baud Rate: 4800-961200 (adjustable)
Working Temperature: -40℃ ~ +85℃
Output Content: 3-axis Acceleration+Angle+Angular Velocity+Quaternion
Range: Acceleration (±16g), Gyroscope (±2000°/s), Angle (X, Z-axis: ±180°, Y ±90°)
