9DOF IMU Sensor GY-85
The GY-85 9DOF IMU Sensor Module is a compact motion tracking device that integrates a 3-axis gyroscope (ITG3205), 3-axis accelerometer (ADXL345), and 3-axis magnetometer (HMC5883L) into a single board. It provides full 9-axis motion sensing, enabling accurate measurement of orientation, tilt, rotation, and magnetic heading. Operating from 3V to 5V, it communicates via the I2C protocol, making it compatible with Arduino and other microcontroller platforms. Its small size and integrated design make it ideal for robotics, navigation systems, drones, and motion tracking applications requiring stable and precise spatial awareness.
تُعد وحدة GY-85 IMU 9DOF وحدة استشعار حركة متكاملة تجمع بين جيروسكوب ثلاثي المحاور (ITG3205) ومقياس تسارع ثلاثي المحاور (ADXL345) ومقياس مجال مغناطيسي ثلاثي المحاور (HMC5883L) في لوحة واحدة. توفر هذه الوحدة قياسًا كاملًا للحركة في 9 محاور مما يسمح بتحديد الاتجاه والدوران والميل بدقة عالية. تعمل بجهد 3 إلى 5 فولت وتستخدم بروتوكول I2C للاتصال، مما يجعلها متوافقة مع الأردوينو والأنظمة المدمجة الأخرى. تُستخدم في الروبوتات والطائرات بدون طيار وأنظمة الملاحة وتتبع الحركة.
The GY-85 9DOF IMU Sensor Module is an advanced motion sensing board designed for accurate tracking of orientation and movement in three-dimensional space. It integrates three key sensors:
- ITG3205 Gyroscope: Measures angular velocity (rotation)
- ADXL345 Accelerometer: Measures linear acceleration and tilt
- HMC5883L Magnetometer: Measures Earth's magnetic field for heading direction
Together, these sensors provide complete 9-degree-of-freedom motion data, making the module suitable for inertial navigation and orientation systems.
The module communicates via the I2C interface, ensuring simple integration with microcontrollers such as Arduino, ESP32, and Raspberry Pi. It includes level shifting circuitry for compatibility with both 3.3V and 5V systems.
With its compact size and stable performance, the GY-85 is widely used in robotics, UAVs, navigation systems, and motion-based control applications.
