Full-featured, Low-noise

The HI05 series is a MEMS-IMU-based sensor system that integrates IMU/VRU/AHRS/INS functionalities. Equipped with our proprietary adaptive Extended Kalman Filter (EKF), dynamic IMU noise analysis algorithm, vehicle motion state analysis algorithm, and GNSS fusion technology, it delivers precise position, attitude, and velocity measurements. HI04 series IMU sensors is attitude sensor with small size and high performance. It can provide users with precise motion information including Euler angles and quaternions, with a temperature range from -40°C to +85°C, suitable for construction machinery, low-speed unmanned driving equipment, humanoid robots, quadrupedal robot applications.
