Inertial Measurement Unit

An Inertial Measurement Unit (IMU) is a sensor module that measures and reports a body's specific force, angular rate, and orientation using a combination of accelerometers, gyroscopes, and sometimes magnetometers. It detects changes in motion, rotation, and position without requiring external references, making it essential for navigation systems, drones, smartphones, and robotics. IMUs provide real-time data about an object's movement in three-dimensional space, enabling applications like motion tracking, stabilization, and autonomous navigation.
