1 Introduction
The WT901SDCL is a multi-sensor device detecting acceleration, angular
velocity, angle as well as magnetic filed. 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 by smart
algorithms.
WT901SDCL’s scientific name is AHRS IMU sensor. A sensor measures 3-axis
angle, angular velocity, acceleration, 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 sensor:
• 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
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

1.1 Warning Statement
Putting more than 5 Volt 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.

2.1.2 Indicator Status
1. 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.
2. After inserting the SD card for about 1 second, the blue light flashes,
indicating that the SD card is recording data.

2.1.3 Software Preparation
Step 1. Unzip the software and install the driver CH340
Link to CH340 driver
Step 2. Plugin the converter to computer and confirm the “com port” in device
manager
Step 3. Open the software(Minimu.exe)
Data will appear after auto-search finishes
Notice: If not successful, please operate manually
Choose the com port and baud rate 9600, data will be shown on the software.
