The HG1120 is a micro-electro-mechanical system (MEMS) based inertial measurement unit (IMU) designed for a range of applications including agriculture, AUVs, industrial equipment, robotics, survey/mapping, stabilized platforms, transportation, UAVs, and UGVs. It features industry-standard communication interfaces, a wide input voltage range, small size, light weight, and low power consumption, making it ideal for diverse system architectures. The HG1120 integrates MEMS gyroscopes, accelerometers, and magnetometers, along with an internal environmental isolation system to mitigate unwanted inputs. Honeywell screens and calibrates all MEMS inertial sensors. Three performance grades are available, with configurable features like output data rate and control signal filtering for simplified integration. The HG1120 is not ITAR controlled, with an Export Control Classification Number (ECCN) of 7A994.
