http://wiki.wit-motion.com/english - 5 - 1 Introduction The WT901SD 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. WT901SD’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. WT901SD is an CE standard accelerometer. It is employed where the highest measurement accuracy is required. WT901SD 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
