Introduction

The WT901 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.

WT901’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. WT901 is employed where the highest measurement accuracy is required. It 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 computers, 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.
VCC cannot connect with GND directly, otherwise it will lead to the burning of the circuit board.
For proper instrument grounding: use WITH MOTION with its original factory-made cable or accessories.
For secondary developing projects or integration: use WITMOTION with its compiled sample code.

**MCU Connection

**

IIC Connection
The WT901 module can be connected to the MCU through the IIC interface. The connection method is shown in the figure below.
Note

To connect multiple modules on the IIC bus, the IIC bus of the module is an open-drain output. When the MCU is connected to the module, the IIC bus needs to be pulled up to VCC through a 4.7K resistor.
VCC is 3.3V, it must be connected to the power supply. Directly using the power supply on the module may cause a voltage drop so that the actual voltage of the module is not 3.3 ~ 5V.
The internal pull-up of the MCU is weak, the driving capacity is limited, and an external pull-up on the hardware is required.
