FSS_IMU16460-B is a 6_DOF MEMS inertial sensor module created by Yuanji Technology. It comes standard with the output of three_axis gyroscope and acceleration information.

High precision and high resolution can capture subtle vibrations and tilts. A wide range of output makes it possible to sense motion under large dynamics. All modules are equipped with ultra_wide temperature range refined temperature compensation and independent calibration before leaving the factory, so that each module can perform stably under various extreme working conditions, while ensuring that the performance of all products is highly consistent.

Application Areas

  • Autonomous driving: vehicle_mounted, robot, engineering vehicle, underwater

  •         Precision measurement: underground, tunnel, vibration, tilt

  •         Stable platform: PTZ, dynamic communication

  •         Automatic control: automatic control system, fixed-wing UAV
