FAQ (Frequently Asked Questions)
-
Q: What should I do if I put more than 5 volts across the sensor wiring?
A: Putting more than 5 volts across the sensor wiring of the main power supply can lead to permanent damage to the sensor. Please ensure that you do not exceed the specified voltage limit. -
Q: Can I use third-party cables or accessories for the instrument grounding?
A: For proper instrument grounding, it is recommended to use WITMOTION’s original factory-made cable or accessories. The use of third-party cables or accessories may not provide optimal performance.

Introduction
The WT901SDCL is a multi-sensor device detecting acceleration, angular velocity, angle as well as magnetic field. The small outline makes it perfectly suitable for industrial retrofit applications such as condition monitoring and predictive maintenance. Configuring the device enables the customer to address a broad variety of use cases by interpreting the sensor data with smart algorithms. WT901SDCL’s scientific name is AHRS IMU sensor. A sensor measures 3-axis angle, angular velocity, acceleration, and magnetic field. Its strength lies in the algorithm which can calculate three-axis angle accurately.
It is employed where the highest measurement accuracy is required. WT901SDCL offers several advantages over competing sensors:
- Heated for best data availability: new WITMOTION patented zero-bias automatic detection calibration algorithm outperforms traditional accelerometer sensor
- High precision Roll Pitch Yaw (X Y Z axis) Acceleration + Angular Velocity + Angle + Magnetic Field output
- Low cost of ownership: remote diagnostics and lifetime technical support by the WITMOTION service team
- Developed tutorial: providing manual, datasheet, Demo video, free software for Windows computer, APP for Android smartphones, and sample code for MCU integration including 51 serial, STM32, Arduino, Matlab, Raspberry Pi, communication protocol for project development
- WITMOTION sensors have been praised by thousands of engineers as a recommended attitude measurement solution
Warning Statement
- Putting more than 5 Volts across the sensor wiring of the main power supply can lead to permanent damage to the sensor.
- For proper instrument grounding: use WITMOTION with its original factory-made cable or accessories
- For secondary developing project or integration: use WITMOTION with its compiled sample code.

Preparation
Connection to the Computer
- This product has an attached Type-C cable that connects the computer and the product. Please use the cable that comes with the product. Use the data cable to connect the product
- Note: The SD card is equivalent to a switch, only when the SD card is plugged in, the sensor can work
Indicator Status
- The product is connected to the power supply. At this time, the power indicator (red) is always on, indicating that the product is charging. The red light will go out after charging is completed.
- After inserting the SD card for about 1 second, the blue light flashes, indicating that the SD card is recording data.
Software Preparation
Unzip the software and install the driver CH340
-
Step 1. Connect the sensor with offered Type-C cable.
(Warm Reminder:If you wanna use a longer cable,it should be a standard Type-C data cable) -
Step 2. Unzip the software and install the driver CH340 https://drive.google.com/file/d/1I3hl9Thsj9aXfG6U-cQLpV9hC3bVEH2V/view?usp=sharing
How to Install and update the CH340 driver
Click the “Uninstall” button first. Then click on the “Install” button.
How to verify your driver is working
- To check that the CH340 enumerates to a COM port, you can open the device manager. You can click the Start or ⊞ (Windows) button and type “device manager to quickly search for the application.
- After opening the device manager, you will need to open the Ports (COM & LPT) tree. The CH340 should show up as USB-SERIAL CH340 (COM##). Depending on your computer, the COM port may show up as a different number.
Type-C Cable Connection
-
Step 1: Insert the SD card, and connect the sensor to the PC with a Type-C cable.
Note: The SD card is equivalent to a switch, only when the SD card is plugged in, the sensor can work.
-
Step 2: Hit the “WitMotion.exe”, and open the software.
-
Step 3: Choose the right Port and product “WT901SDCL”.
-
Step 4: You can set configuration in the Config.
Record the data
- Step 1: Please hit the “Record”, then hit “Record data”.
- Step 2: Please choose the format of data you need, then hit “Start Record”.
- Step 3: You can check the following five files: TXT\CSV\Play\raw-data\Mat
Playback data

Offline Record
Guidelines
- Offline record requires the configuration of calibrating time. So the data will have a “Time” to know when the data starts to be recorded. There will be a 16G SD card and an SD card reader that comes with the sensor as an accessory.
- In this product, the SD card is mainly used to record data. Only when the SD card is inserted will the product start to work and the data will be transferred.
- Each time an SD card is inserted, the data will be getting recorded. The data will be stored in the SD card as text. The LOG with the largest number is the latest file.

Note:
The TXT format of the offline record is garbled, please record the playing
data to get the raw data.
When the data is playing back, click on the “Record data” to get the original data such as csv/txt/play. (Please refer to chapter 4.1)
- Step 1. Disconnect with the computer (Unplug the cable)
- Step 2. Insert the SD card into the sensor, the sensor will start to record the data.
- Step 3. Remove the SD card and insert it into the card reader, than you can check the recoding file as txt.
- Step 4. Plugin the reader Open the software, and click the “Record”, then click the method of playback.
- Step 5. Select the recorded file from the USB Drive path and load the recorded file, click “Start playing” and data will be playback.
