Product Description

BW-IMU127C Series Low-Cost Modbus Inertial Measurement Unit RS232 /485/TTL 




BW-IMU127C uses highly reliable MEMS accelerometers and gyroscopes, and it uses algorithms to ensure measurement accuracy.

It has a digital interface, which can be easily integrated into the user's system, and it uses algorithms to ensure measurement accuracy. At the same time, the sealing design and strict production process ensure that the product can accurately measure movement parameters such as the angular velocity, acceleration and attitude of the carrier in harsh environments.
