1、Product Description

FSS-IMU614E-G is a MEMS inertial measurement unit (IMU) module with 6 degrees of freedom (DOF) developed by Forsense (Shanghai) Technology Co., Ltd.


It features 3-axis Gyroscopes and 3-axis Accelerometers, measuring angular velocity, linear acceleration, and high-precision attitude angles respectively.


High precision and high resolution combine to help capture subtle vibration and tilt. A large number of output parameters enable the perception of motion despite intense shaking. All IMU modules are calibrated independently on a rotary table and adjusted precisely over an ultra-wide temperature range in a temperature chamber before leaving the factory, so that they can deliver stable and consistent performance in most extreme conditions.
