What's IMU ? How is the difference between IMU Sensor and Gyroscopes?

IMU sensor stands for inertial measurement unit.IMUs are mostly used in devices that require motion control, such as cars and robots.It is also used in the application of precision displacement calculation with attitude, such as inertial navigation equipment of submarine, aircraft, missile and spacecraft, etc.

 

 

An inertial measurement unit (IMU) is a device that measures the attitude Angle (or angular velocity) and acceleration of an object on three axes.In general, an innovative marketing includes three accelerometer of single shaft and single axis of gyroscope and accelerometer to detect objects in the vehicle coordinate system independent triaxial acceleration signal, and relative to the navigation coordinate system of the angular velocity gyroscope detection carrier signal, measuring angular velocity and acceleration of objects in three-dimensional space, calculated and objects.

 

The difference between IMU and gyroscope

With the continuous development of modern microelectronics technology, the original mechanical gyroscope can now be made very small, small enough to be put into a mobile phone.Mid - and high-end smartphones are now widely equipped with MEMS inertial measurement units (IMUs) for navigation, function control and gaming.

Gyroscope:

Gyroscope is an instrument to measure the angular motion of an object.By measuring the offset of the biaxial base point of the gyroscope in different motion states, the horizontal, vertical, pitch, acceleration, course and azimuth of the object can be calibrated.
