Overview
1. This product is a high-performance two-axis motion attitude measurement system based on MEMS technology. It contains a three-axis gyroscope, a three-axis accelerometer, and a motion sensor. By integrating various high-performance sensors and using the independently developed attitude dynamics core algorithm engine, combined with the high-dynamic Kalman filter fusion algorithm, the MEMS high-precision module can directly output the inclination angle.
2. The leading sensor fusion algorithm based on the Kalman filtering principle and with independent intellectual property rights can provide data with an update rate of up to 200Hz in real time, thereby meeting various high-precision application requirements and achieving accurate motion capture and attitude estimation.
3. It has the country's leading high-precision turntable equipment and instruments, and the products integrate self-developed high-precision calibration and calibration algorithms to improve the measurement accuracy of the products.
4. The SIN series products are inclination sensors developed and produced by Shenzhen Weite Intelligent Technology Co., Ltd., with a built-in high-precision inclination measurement unit. By measuring the static gravity acceleration, it is converted into inclination changes, so that the inclination and pitch angle of the sensor output relative to the horizontal plane can be measured. . The output mode is RS232, RS485 or TTL level interface standard optional. This product has high precision. It has good stability and is easy to use, and is widely used in industrial inclination measurement. It is an ideal choice for industrial automation control and platform attitude measurement. It has strong resistance to external electromagnetic interference and can adapt to long-term work in harsh industrial environments.
5. At the same time, we provide various host computers, operating instructions, development manuals, and development codes that users need to minimize the research and development time for various needs.
