ER-MIMU-07 Stable-control MEMS IMU
Introduction
ER-MIMU-07 is the world’s smallest triaxial MEMS IMU. Inertial Measurement Unit, referred to as IMU, is a device to measure the attitude angle (or angular velocity) and acceleration of the three axis of the object. With the built-in accelerometer sensor and gyroscope, the IMU can measure the linear acceleration and rotation angular velocity from three directions and can obtain the attitude, velocity and displacement information of the carrier through the resolving.
