1 Introduction
The WT901 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.
WT901’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.
WT901 is employed where the highest measurement accuracy is required.
It 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
