IMU 10DOF Sensor Module MPU9250 BMP280 ( GY-91 )
Out Of Stock
The GY-91 IMU 10DOF Sensor Module combines the MPU9250 9-axis motion sensor and BMP280 barometric pressure sensor into a single compact unit. It measures acceleration, angular velocity, magnetic field, and atmospheric pressure, making it ideal for advanced motion tracking and environmental sensing applications. The module supports accelerometer ranges up to ±16g, gyroscope ranges up to ±2000°/s, and magnetometer sensing up to ±4800µT, with pressure detection from 300–1100 hPa. Operating at 3–5V, it is widely used in drones, robotics, navigation systems, and IoT devices requiring accurate orientation, altitude, and motion data.
تُعد وحدة GY-91 IMU 10DOF وحدة استشعار متقدمة تجمع بين حساس الحركة MPU9250 ذو 9 محاور وحساس الضغط الجوي BMP280 في لوحة واحدة مدمجة. تقوم بقياس التسارع، والسرعة الزاوية، والمجال المغناطيسي، إضافة إلى الضغط الجوي، مما يجعلها مناسبة لتطبيقات تتبع الحركة والملاحة وقياس الارتفاع. تدعم مدى تسارع يصل إلى ±16g، ومدى جيروسكوب حتى ±2000 درجة/ثانية، ومجال مغناطيسي حتى ±4800µT، مع قياس ضغط من 300 إلى 1100 hPa. تعمل بجهد 3 إلى 5 فولت وتستخدم في الطائرات بدون طيار والروبوتات وأنظمة الملاحة والمشاريع الذكية.
The GY-91 MPU9250 + BMP280 10DOF IMU Sensor Module is an advanced multi-sensor unit designed for precise motion tracking, orientation sensing, and environmental measurement. It integrates two powerful sensors:
- MPU9250: A 9-axis IMU combining a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer.
- BMP280: A high-precision barometric pressure sensor used for altitude estimation.
The module provides digital data output through I2C communication and includes a built-in 16-bit ADC for high-resolution measurements. It is widely used in robotics, UAV flight control, navigation systems, and wearable devices where accurate spatial awareness is required.
With its compact size and low power consumption, the GY-91 is ideal for embedded systems that require full motion tracking, heading direction, and altitude sensing in a single module.
