Technical details and manufacturing context for Precision Inertial Measurement Unit (IMU) Sensor Module

Definition
A compact, integrated sensor module that combines accelerometers and gyroscopes to measure linear acceleration and angular rate across multiple axes. It serves as the fundamental motion-sensing core within larger navigation, guidance, and stabilization equipment. This component provides raw inertial data to a host system's processor for calculating position, orientation, and velocity. It is critical for applications requiring precise motion tracking without external references.
Working Principle
Utilizes micro-electromechanical systems (MEMS) accelerometers to detect linear acceleration via capacitive sensing of a proof mass, and MEMS gyroscopes to detect angular rate via the Coriolis effect on vibrating structures, outputting digital signals proportional to measured forces.
