Product Introduction
The MSI310K micro inertial measurement unit is a high-range, miniaturized inertial sensor module that integrates three-axis gyroscopes and three-axis accelerometers. By implementing temperature compensation for the zero bias and scale factor of each axis, its measurement accuracy is significantly enhanced. Additionally, it features built-in high-range sensing elements, providing a wide acceleration measurement range.
