Product Description

BW-IMU127 Series Low-cost Modbus Inertial Measurement Unit RS232 /485/TTL



BW-IMU127 has a digital interface, which can be easily integrated into the user's system.It uses highly reliable MEMS accelerometers and gyroscopes, and it uses algorithms to ensure measurement accuracy. The data deviation is estimated by the 6-state Kalman filter with appropriate gain, which is suitable for inertial attitude measurement in motion or vibration state.
