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, using the independently developed attitude dynamics core algorithm engine, and combining it 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 filter principle and with independent intellectual property rights can provide data with an update rate of up to 200Hz in real time to meet the needs of various high-precision applications and achieve accurate motion capture and attitude estimation.
3. We have the leading domestic 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. SIN series products are inclination sensors developed and produced by Shenzhen Weite Intelligent Technology Co., Ltd., with built-in high-precision inclination measurement unit. By measuring the static gravity acceleration and converting it into a change in inclination, the inclination and pitch angles of the sensor output relative to the horizontal plane can be measured. . The output modes include RS232 and TTL level interface standards. This product has high precision. It has good stability and is easy to use, and is widely used in industrial inclination measurement. It is ideal for industrial automation control and platform attitude measurement. It has strong ability to resist 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 required by users to minimize the development time for various needs.
