# The Difference between Tilt Sensor and Gyro Sensor

The tilt sensor senses the angle of inclination deviation, only data feedback but no command feedback.

The gyroscope measures the angular velocity, senses the action variable, and then controls the steering gear to carry out the repair action command.

The tilt sensor uses Newton's second law as its working principle. According to the law, we know that when the inclination sensor is stationary, because the side of the object and the vertical direction are affected by other forces, only the action of gravity, that is to say, it acts on the all it has on it is the acceleration of gravity. Therefore, the resulting angle between the vertical axis of gravity and the sensitive axis of the acceleration sensor is what we call the inclination angle, which is the angle we seek.

Tilt sensors are divided into three different working principles and are divided into three types. The first type of inclination sensor is the solid pendulum type, the second type of inclination sensor is called the liquid pendulum type, and the last type of inclination sensor is the gas pendulum type. The working principles of these three different types of inclination sensors will be different. Because of their different working principles, they will have different advantages and disadvantages.

No matter which type of tilt sensor it is, it will be substantially different from a gyroscope. Like inclination sensors, no matter which type it is, it measures the inclination angle at rest. Compared with the inclination sensor, the gyroscope measures the inclination in motion, and the measurement result of the inclination in static is not accurate. So when we measure the inclination in our daily life, whether to choose the inclination sensor or the gyroscope, we can choose according to this essential difference. If the inclination is measured at rest, then the inclination sensor must be selected, and the inclination in motion is measured, and of course the gyroscope is selected. The specific differences are summarized as follows:

1.Different definitions

The gyroscope is an angular motion detection device that uses the momentum moment-sensitive shell of a high-speed revolving body relative to the inertial space around one or two axes that are orthogonal to the axis of rotation. There are many varieties of gyroscopes, which can be divided into sensing gyroscopes and indicating gyroscopes according to their uses. The ER-MG2-022 is a single-axis MEMS angular rate sensor (gyroscope) capable of measuring angular velocity up to a maximum of ±100°/s with digital output compliant to SPI slave mode 3 protocol.  Angular rate data is presented as a 24-bit word, intended for north seeking applications.  An advanced, differential sensor design rejects the influence of linear acceleration, enabling the ER-MG2-022 to operate in exceedingly harsh environments where shock and vibration are present.

The sensor gyroscope is used in the automatic control system of the flying body movement, as a horizontal, vertical, pitch, heading and angular velocity sensor. The indicating gyroscope is mainly used for the indication of the flying condition, and is used as a driving and piloting surface.

2.Different functions

The tilt sensor measures the inclination of all stops. Compared with the inclination sensor, the gyroscope measures the inclination angle during the movement, and the measurement result of the inclination angle in the static state is inaccurate. The gyroscope is not a measuring device, but an auxiliary device. Just like the tank barrel, in order to allow the tank to shoot accurately during the trek, a gyroscope is installed to automatically control the viewpoint of the barrel.

3.Different applications

The tilt sensor is often used for the level measurement of the system. From the working principle, it can be divided into three types of inclination sensors: "solid pendulum", "liquid pendulum" and "gas pendulum". The inclination sensor can also be used to measure the inclination relative to the horizontal plane. The amount of change.

The gyroscope sensor was originally used on the helicopter model, and it has been widely used in mobile portable devices such as mobile phones. Not only that, the modern gyroscope is an instrument that can accurately determine the orientation of moving objects, so the gyroscope Sensors are essential controls in modern aviation, marine, aerospace and defense industrial applications.
