Waterproof and dustproof with IP67 rating. Wireless industrial-grade measurement. Accurate posture output using advanced Kalman filtering.

"Achieving high-precision measurement in harsh environments, industrial wireless IMU" The LPMS-IG1W is a high-performance 6-axis inertial measurement unit (IMU) compatible with Bluetooth connections. In addition to measuring 3 axes each of acceleration and gyroscope, it outputs precise attitude angles even in dynamic environments through advanced algorithms. - High robustness that is not limited by the environment (IP67 standard) It features a fully waterproof and dustproof aluminum housing. This allows for measurements in harsh locations such as outdoor construction sites, dust-heavy factories, vessels exposed to splashes, agricultural machinery, and rotating bodies. - High-precision measurement with proprietary algorithms Equipped with the Kalman filter "Core Fusion Engine" based on years of research. It corrects for severe vibrations and magnetic interference in real-time, outputting stable attitude angles with minimized drift at up to 400Hz. - Maximizing development efficiency with complete wireless operation (ROS/ROS2 compatible) It operates completely cable-free with an internal battery and Bluetooth. Ideal for large machinery where wiring is difficult and for human body measurements. In addition to Linux compatibility, it officially supports ROS/ROS2 drivers, facilitating smooth integration into autonomous driving systems.
