【 What You Get 】1 x WitMotion WT61C RS232 Accelerometer sensor+ 1* 4-PIN Dupont cable +1 x Welcome guide (USB-UART converter not included )
WT61C’s scientific name is the AHRS IMU sensor. A sensor measures 3-axis angle, angular velocity, acceleration. WitMotion WT61C integrates a high-precision gyroscope, accelerometer, 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
Voltage: 5V (requiring a power source of 5V)
Data Output Frequency：20Hz / 100Hz
Baud Rate: 9200 / 115200
Output Content: 3-axis Acceleration+Angle+Angular Velocity
Range: Acceleration (±6g), Gyroscope (±2000°/s), Angle (X, Z-axis: ±180°, Y ±90°)
Resolution: Acceleration (0.005g), Gyroscope (0.61°/s)
Angle Accuracy(after calibrated): X, Y-axis: 0.05° (Static) , X, Y-axis: 0.1° (Dynamic)
Note: Because the Z-axis angle is calculated and anylyzed via the gyroscope. There will be acculated error on Z-axis angle by time when moving. It is required to calibrate.
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.
