Description

bluetooth accelerometer acceleration sensor gyroscope gyro magnetometer mpu6050 mpu9250 inclinometer

Highlights

WT61’s scientific name is the AHRS IMU sensor. A sensor measures 3-axis angle, angular velocity, acceleration. Its strength lies in the algorithm which can calculate the X and Y axis angle accurately.

Robust MEMS design and small in size
Ground breaking bias stability, low noise level
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: <10mA
Voltage: 3.3-5V (requiring a power source of 3.3-5V)
Data output frequency：20Hz / 100Hz
Baud Rate: 4800-230400
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.
