Accelerometer is one of the basic measurement components of inertial navigation and inertial guidance system. Accelerometer is essentially an oscillation system, which is installed inside the moving carrier and can be used to measure the acceleration of the carrier.The three-axis accelerometer is based on the basic principle of acceleration to achieve work. Acceleration is a space vector. On the one hand, to accurately understand the motion state of an object, the components on its three axes must be measured. On the other hand, When the direction of motion of the object is known, only the three-axis acceleration sensor is used to detect the acceleration signal, and since the three-axis acceleration sensor is also based on the gravity principle, the three-axis acceleration sensor can realize two-axis plus or minus 90 degrees or two-axis 0- The 360 degree inclination angle is higher than the two-axis acceleration sensor by the correction angle of 60 degrees.The three-axis accelerometer has the advantages of high accuracy, small size, low power consumption, etc. It can provide accurate motion information, and can be used for motion control on smart phones, and it is small in size, low power consumption, and can save energy.ER-QA-03A high-performance quartz accelerometer can measure the range of ±50g, bias repeatability ≤10μg, scale factor repeatability ≤15ppm.
The three-axis gyroscope is also called "micro-mechanical gyroscope", and the "micro-mechanical gyroscope" can also be called "MEMS gyroscope", that is, the position of six directions is simultaneously measured, the moving track is accelerated, and the single-axis can only be measured. The amount in one direction, that is, one system requires three gyroscopes, and one of the three axes can replace three single axes. The 3-axis has a small volume, light weight, simple structure and good reliability, and is a development trend of the laser gyro. In short, the biggest role of a three-axis gyroscope is to “measure angular velocity to determine the motion state of an object, so it is also called a motion sensor.” In other words, this thing allows our device to know where it is and where it goes. where"
The three-axis accelerometer can be used in a variety of different applications, it can be used in the testing of automotive and aerospace products, but also can be used for motion control on smartphones and tablets. It can be used to detect the motion state of objects, as well as measure the acceleration of objects in real time, so as to better control their movement. Through the real-time monitoring of the three-axis acceleration sensor, people can quickly locate the accurate position and direction of the object in the three-dimensional space. The data of the three-axis acceleration sensor can provide heavy gravity and acceleration, and then the position and direction of the object in different directions can be determined. For example, a three-axis acceleration sensor can be used to Orient an object to guide a moving robot, operate a drone, etc., to control the object. The three-axis acceleration sensor can also be used for automatic control and adjustment of the motion state of machines and robots. The gate control system can use these sensors to open or close the door according to the needs of the user, and has high-precision control capabilities.
