    Introduction

    ER-2MG-01/01mini 2-Axis North-Seeking MEMS Gyro

    Introduction
    The ER-2MG-01/01 mini 2-Axis North-Seeking MEMS Gyro has small volume, light weight, simple structure and good reliability. The biggest function of the two-axis gyroscope is to “measure the angular velocity to judge the motion state of the object, so it is also called a motion sensor”. In other words, this thing can let our equipment know where we are and where we are going.

    Application
    Construction machinery dip angle measurement, angle control, pylon operation monitoring, medical equipment angle control, satellite antenna star search, bridge, tall building, tower, dam monitoring and rock and soil monitoring, mining, attitude/heading reference system, integrated inertial navigation.
