Product Description

Highlights
WT901C’s scientific name is the AHRS IMU sensor. A sensor measures 3-axis angle, angular velocity, acceleration, magnetic field. WitMotion WT901C integrates a high-precision gyroscope, accelerometer, and geomagnetic field sensor, and adopts a high-performance microprocessor, advanced dynamics fusion algorithm, and Kalman dynamic filtering algorithm to quickly analyze the module's current real-time motion posture.
- By WitMotion advanced digital filtering technology, the sensor can effectively reduce measurement noise and improve measurement accuracy
- With its in-built posture solver and the dynamic Kalman filter algorithm, the sensor can 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°, and the stability is extremely high.
- 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
Technical Specifications:
- Current: <40mA
- Voltage: 5-36V (requiring a power source of 5V)
- Data output frequency:0.2-200Hz
- Baud Rate: 4800-230400 (adjustable)
- Output Content: 3-axis Acceleration+Angle+Angular Velocity+Magnetic Field+Quaternion
- Range: Acceleration (±6g), Gyroscope (±2000°/s), Magnet Field (±4900µT), Angle (X, Z-axis: ±180°, Y ±90°)
- Resolution: Acceleration (0.005g), Gyroscope (0.61°/s), Magnet Field (16 bits)
- Angle Accuracy(after calibrated): X, Y-axis: 0.05° (Static) , X, Y-axis: 0.1° (Dynamic)
Note: Z-axis angle will be affected by magnetic field. It is required to calibrate and keep the sensor at least 20cm away from the stuff like metal that may create magnetic field interference.
The bulk inquiry is welcome. Production capacity is 10,000pcs / month. If you have any interest or need any help, please feel free to reach us.
