The LKF-HH3001 High Dynamic Performance MEMS IMU features triaxial MEMS gyroscopes for angular motion detection and triaxial MEMS accelerometers for linear acceleration measurement. The system includes comprehensive temperature compensation for zero bias, scale factor, and inter-axis non-orthogonal errors, with software-adjustable internal low-pass cutoff frequency. These advanced features ensure sustained high measurement accuracy across the full operating temperature range of -40℃ to 85℃, even during rapid temperature changes (≤1℃/min).
With an output data rate (ODR) of 1000Hz and a measurement delay of only 7ms, the LKF-HH3001 delivers real-time motion data capture, making it ideal for high-dynamic application scenarios. The system supports flexible software configurations to meet diverse user requirements.
