1 Introduction
The WTGAHRS2 is a multi-sensor device detecting acceleration, angular
velocity, angle, magnetic filed as well as GPS. The robust housing and 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.
WTGAHRS2’s scientific name is GPS
IMU sensor.
A sensor measures 3-axis
angle, angular velocity, acceleration, magnetic field and GPS data. Its strength
lies in the algorithm which can calculate three-axis angle accurately.
WTGAHRS2 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+GPS data
• 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
