EPSON X2A0002710002 XV7011BB Characteristics and uses of the gyroscope sensor

Gyroscope sensors are used in many areas. If used on the camera of the phone, to prevent the impact of jitter on the image quality. For example, when there is no GPS signal in the car driving process, you can measure the yaw or the linear movement displacement of the car through the gyroscope, so as to continue navigation.

 Gyro sensors have a MEMS (microelectromechanical system) gyroscope and a QMEMS gyroscope. At present, MEMS (microelectromechanical system) gyroscope is common, so what is QMEMS gyroscope? QMEMS Is Epson's patented technology. Put the quartz in the AC electric field, when the AC electric field matches the quartz natural frequency, resonance will be generated. Gyroscope sensor output is angular speed, to get through the integral, but even in zero input state, gyroscope sensor affected by temperature is still have output, its output is white noise and slow random function superposition, therefore, in the process of integral, will introduce the cumulative error, the longer the integral time, the greater the error. Because of the excellent temperature stability of quartz crystal, the QMEMS gyroscope sensor that combines it with MEMS has very good temperature drift performance, greatly improves the difference, and realizes the stable temperature characteristics of angular velocity output in the stationary state.

 XV7011BB The gyroscope sensor is a uniaxial digital support SPI and I2C serial interface, providing 16bit or 24bit angular velocity output, with excellent zero-bias stability to temperature. Its operating temperature range is-20°C to + 80°C (optional-40°C to + 85°C), with a built-in temperature sensor, and a built-in digital filter is optional. In addition, the output deviation of the sensor at rest is as low as ± 1° / s (typical value 0 LSB), the output temperature deviation is only ± 1° / s and a linearity of ± 0.5%FS. Unlike the silicon material used in gyroscopes using MEMS technology, XV7011BB is a quartz material. When the product rotates, XV7011BB detects the angular velocity by the Coriolis force applied to the vibrating element, which greatly improves the deviation and realizes the stable temperature characteristic of the angular velocity output in the stationary state. In the intelligent sweeping robot, the gyroscope XV7011BB excellent temperature drift characteristics, help the sweeping robot path planning and actual operation more accurate. When solving the problem of intelligent lawn mower, engineers often add gyroscope sensors to realize the road strength planning of the lawn mower. Through the gyroscope to measure the Angle change of the lawn mower, and control the direction of the lawn mower, XV7011BB can well solve the problem of path planning of the intelligent lawn mower.

XV7011BB Because of its low power consumption, small size and flexible mode, the gyroscope sensor is widely used in intelligent wearable devices, sorting robot, AGV logistics robot car and intelligent sweeping robot and other fields, these applications show its advantages in the need for accurate Angle measurement and low power consumption solutions.

 XV7011BB The gyroscope sensor is designed to adopt high stability bias output stability and low noise characteristics based on the proprietary QMEMS technology, which enables it to maintain stable performance in various environments. Furthermore, with a detection range of ± 100° / s, voltage operating range of 2.7-3.6V and size of 5.0 x 3.2 x 1.01.3 mm, these specifications make it ideal for multiple application scenarios

In conclusion, the EPSON X2A0002710002 XV7011BB gyroscope sensor plays an important role in multiple fields with its excellent performance, wide applicability, and unique technical features.
