FSM-9 and FSM-9 OEM Freespace® Sensor Modules

Hillcrest's FSM-9 and FSM-9 OEM are compact modules containing state-of-the-art MEMs technology including tri-axial gyroscopes, tri-axial accelerometers, and tri-axial magnetometers

Hillcrest’s FSM-9 is a low-cost, battery operable, fully calibrated inertial measurement unit (IMU)/attitude heading reference system (AHRS). The FSM provides a simple, highly cost-effective solution for integrating accurate, multiaxis inertial sensing into a wide range of consumer and industrial applications, eliminating the complexity and investment associated with a discrete design. This compact module contains state-of-the-art MEMs technology including a tri-axial gyroscope, a tri-axial accelerometer, and a tri-axial magnetometer. Combining these sensors with the onboard Hillcrest Freespace MotionEngine™ Processor, the FSM-9 provides precise real-time 3D orientation, heading, calibrated acceleration, and calibrated angular velocity, as well as more advanced outputs such as cursor.

Complete Inertial Motion Tracking System Compact Design
  • Tri-axial accelerometer, gyroscope, and magnetometer enable complete motion tracking
