Specification

WitMotion Bluetooth 2.0 AHRS BWT61 6 Axis Sensor Digital Tilt Angle   Accelerometer   Gyro MPU6050 Inclinometer For PC/Android

Technical Specifications:

BWT61CL’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 three-axis angle accurately. The robust housing and the small outline makes it perfectly suitable for industrial retrofit application such as motion capturing, engineering machine monitoring, etc.

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.

Current: <40mA

Working Temperature: -40℃ ~ +85℃

Battery life: about 4 hours

Data output frequency:100Hz

Interface: Type-C, Bluetooth 2.0

Baud Rate: 115200 (default, can not be changed)

Voltage: 3.3-5V, built-in rechargeable battery (260mAh capacity, 3.7V)

Output Content: 3-axis Acceleration+Angle+Angular Velocity

Range: Acceleration (±16g), 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)

Angle of Z-axis will have accumulated error under working
