North-Seeking Mems Imu for Gyro Tools

ER-MIMU-091 North-Seeking MEMS IMU for Gyro Tools

Introduction
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 rapid development of science and technology, MEMS IMU is increasingly widely used in the fields of oil and mining, injecting new vitality into this traditional industry. This is a high-performance product specially designed for oil drilling, mining and other fields. Based on three-axis integrated MEMS gyro and three-axis accelerometer, ER-MIMU-091 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.
