This user manual covers the installation, wiring, and debugging of the BWSensing BW-IMU127 series low-cost Modbus inertial measurement unit.
The BWSensing BW-IMU127 is a high-precision strapdown inertial measurement unit designed to measure angular velocity and acceleration parameters. It utilizes MEMS accelerometers and gyroscopes with algorithms such as 6-state Kalman filtering, nonlinear compensation, orthogonal compensation, temperature compensation, and drift compensation to ensure accuracy in motion or vibration states. The device features digital interfaces (RS232/485/TTL) for easy integration into user systems. This manual is written in Chinese.
