Did you know?
WebThis accelerometer is composed by a polysilicon surface-micromachined capacitive sensor and a conditioning electronic stage that implements an open-loop measurement architecture. Acceleration deflects the moving mass and unbalances the differential capacitor resulting in a sensor output whose amplitude is proportional to acceleration. Web1.6 Attitude & Heading Reference System (AHRS) An attitude and heading reference system (AHRS) uses an inertial measurement unit (IMU) consisting of microelectromechanical system (MEMS) inertial sensors to measure the angular rate, acceleration, and Earth's magnetic field. These measurements can then be used to derive an estimate of the object ...
