Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

STMicroelectronics' innovative inertial measurement unit LSM6DSV80XTR integrates two accelerometers with full scales of 16g and 80g, a gyroscope with a full scale of 4000dps, and an embedded intelligent core in a single package. This new type of sensor can measure various events ranging from slight movements to strong impacts with the same accuracy, achieving enhanced functions in wearable devices and motion trackers and other equipment.

Product Introduction

The LSM6DSV80XTR 6-axis inertial measurement unit (IMU) integrates two accelerometer structures in a single component, enabling full-range sensing of 16g and 80g, embedded intelligence, and gyroscopes up to 4000dps. With the LSM6DSV80XTR, the device can offer functions such as training analysis and performance benchmarking, providing assistance to athletes. The low-G accelerometer records and recognizes activities such as running, walking and gesture interactions. This IMU is suitable for various applications of sports equipment.

In addition to the advanced accelerometer architecture, the LSM6DSV80XTR also integrates a MEMS gyroscope and digital processing capabilities using sensor fusion Low Power (SFLP) technology, enabling spatial direction and gesture detection. Machine learning kernels (MLC) and finite state machines (FSMS) can provide edge processing in sensors, thereby enhancing performance and reducing power consumption. The LSM6DSV80XTR IMU can process raw data locally, enabling a broader analysis of sports training.
