Product Description
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 X and Y 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)
Note: There will be acculated error on Z-axis angle by time when moving. It is required to calibrate.
Hardware Analysis (In-built BWT61)
| Plastic Casing
| WITMOTION Alrogithm AdvantagesWITMOTION products are derived from the aerospace Satellite Attitude Determination Algorithm. Built-in core algorithm:
Time and energy saving: No need to write a filtering program or study the complicated protocol of MPU6050/ 9250 to analyze and collect the attitude angle data. | Multiple-Connection
Notice: 1. The multiple-connection is required to buy the tool, USB-HID adapter from Witmotion store. (search ASIN: B07PXQJ4PW ) 2. Each BWT61CL can only pair with 1 USB-HID adapter. (note: the USB-HID need install CH340 drive) |

Genuinely Useful Software
WITMOTION software offers several advantages:
- configurations setting
- dashboard, 3D DEMO, data curve & chart display in real-time
- data record and playback, raw data reviewing, and more
Notice: There is no software for the Linux, Python, or Mac system at present. Witmotion software is provided, compatible with the Windows system only, including Win 10, 8, 7, XP.
3D DEMO
More intuitive to view the sensor’s motion state. There are 4 types of simulation, car, head, plane, cube. The source code of 3D can be provided if customers have needs.
Three methods for connection sensor with Windows PC:
- Bluetooth wireless connection: through USB-HID adapter. (driver-free, no need pairing), Recommended tool: B07PXQJ4PW
- Wiring Connection: universal Type-C data cable (need to install CH340 driver)
- Wireless Bluetooth connection via PC and sensor(need pairing)
Rock-solid data measurement in real-time
The motion changing of the sensor will show on the data curve in real-time.
Much easier and convenient for data collection and application.
- The data can be recorded by simply click the “record” button.
