The MIMU-K Micro Inertial Measurement Unit (IMU) is a compact, high-performance and cost-effective MEMS inertial sensor, designed to capture the three-dimensional angular velocity and acceleration of moving carriers.
Embedded with integrated full-temperature compensation, misalignment angle compensation and nonlinear compensation algorithms, the MIMU-K maintains superior and stable performance under both static and vehicle dynamic working conditions. It delivers highly consistent and reliable measurement data even in complex and harsh service environments.
