Inertial sensors are devices that measure the specific force, angular rate, and sometimes the magnetic field surrounding them. They are commonly used in various applications, including smartphones, drones, and vehicles, to detect motion and orientation. These sensors help in navigation, stabilization, and control by providing real-time data about movement. The most common types of inertial sensors are accelerometers and gyroscopes. Accelerometers measure linear acceleration, while gyroscopes measure rotational motion. Together, they enable systems to understand their position and movement in three-dimensional space, making them essential for technologies like GPS and augmented reality.
