Introduction

Low-cost 3 axis MEMS Gyro

Introduction
The ER-3MG-184 Low-cost 3 axis MEMS Gyro is small in size, light in weight, simple in structure and has good reliability. The dual-axis gyroscope has the greatest function of providing the angular velocity needed to determine the motion state of an object, and thus is also called a motion sensor.

Feature
Low cost
Gyro bias instability: 1 deg/hr
Gyro bias stability (10s 1σ): 5 deg/hr
Gyro angle random walk: 0.25 °/√h

Application
Including agriculture, AUV, industrial equipment, robots, surveying, stabilization platforms, transportation, unmanned aerial vehicles (UAVs) and unmanned ground vehicles (UGVs).
