## Features

- 3-axis angular rate sensing: detect rotational angular velocity to capture rotation and sway of equipment

- 3-axis acceleration sensing: measure gravity, vibration, shock and linear acceleration

- Foundation for attitude calculation: gyroscope and accelerometer data fusion to output attitude angles, tilt angles and heading

- Comprehensive built-in self-monitoring for real-time sensor status verification, suitable for safety-critical applications

- Timestamp + SYNC synchronization function for synchronous sampling in multi-sensor networks

- Excellent zero-point stability under high/low temperature and heavy vibration conditions to reduce drift error

## Applications

- Inertial navigation IMU and positioning systems (agricultural machinery, construction machinery, marine instruments)

- Attitude control for industrial robots and mobile equipment

- UAV flight control and gimbal stabilization

- Attitude monitoring for construction machinery and agricultural machinery

- Surveying instruments and geological monitoring equipment

- Dynamic tilt monitoring for vehicles and heavy-duty equipment

## Comparison
