1Introduction
The WT9011DCL-BLE5.0 is a multi-sensor device detecting acceleration,
angular velocity, angle as well as magnetic filed. The robust housing and the
small outline makes it perfectly suitable for industrial retrofit applications
such as condition monitoring and predictive maintenance. Configurationuring
the device enables the customer to address a broad variety of use cases by
interpreting the sensor data by smart algorithms.
WT9011DCL-BLE5.0’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 the three-axis angle
accurately.
It is employed where the highest measurement accuracy is required.
WT9011DCL-BT5.0 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
•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.
Do not access the I2C interface.
Do not change the baud rate because WitMotion
Bluetooth sensor’s baud rate is fixed.

3.1.1 Serial Connection
Step 1. Connect the sensor with offered Type-C wire.
(Warm Reminder:If you wanna use a longer cable, it should be a standard
Type-C data cable)
Step 2. Install the driver- CH340
Download Link
*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
1）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.
2）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.
