Product Model:
MSI310K
Product Features
● Miniaturized IMU
● Wide range
● Low power consumption
● High cost performance
● Full Temperature Compensation
● High stability
Product Introduction
The MSI310K micro inertial measurement unit is a high‑range, miniaturized inertial component that integrates three-axis gyroscopes and three-axis accelerometers. By performing temperature compensation for the zero bias and scale factor of each axis, its measurement accuracy is significantly enhanced, while its built‑in high‑range sensing elements provide a wide acceleration range.
