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