1 Introduction

The SINDT is a multi-sensor device that detects acceleration, angular velocity, and angle. Its robust housing and small outline make it perfectly suitable for industrial retrofit applications such as condition monitoring and predictive maintenance. Configuring the device enables customers to address a broad variety of use cases by interpreting the sensor data through smart algorithms.

SINDT's scientific name is AHRS IMU sensor. It measures 3-axis angle, angular velocity, and acceleration. Its strength lies in its algorithm, which can accurately calculate dual-axis angles.

Advantages over Competing Sensors:

Heated for best data availability: Features a new WITMOTION patented zero-bias automatic detection calibration algorithm that outperforms traditional accelerometer sensors.
High precision: Measures Roll, Pitch, Yaw (X Y Z) Acceleration, Angular Velocity, and Angle.
Low cost of ownership: Includes remote diagnostics and lifetime technical support from the WITMOTION service team.
Comprehensive development resources: Offers tutorials, datasheets, demo videos, free software for Windows computers, an Android app, and sample code for MCU integration (including 51 serial, STM32, Arduino, Matlab, Raspberry Pi), along with communication protocols for project development.
Industry Recognition: WITMOTION sensors are praised by thousands of engineers as a recommended attitude measurement solution.

1.1 Warning Statement

Please observe the following warnings to prevent damage to the sensor:

Applying more than 5 Volts across the sensor wiring of the main power supply can lead to permanent damage to the sensor.
VCC must not be connected directly to GND, as this will lead to the burning of the circuit board.
For proper instrument grounding, use WITMOTION with its original factory-made cable or accessories.
Do not access the I2C interface.
For secondary development projects or integration, use WITMOTION with its compiled sample code.
