The Yost Labs 3-Space Sensor™ Mini Bluetooth is a small, high-precision, high-reliability, low-cost, wireless, dual mode Bluetooth/LE, SMT Attitude and Heading Reference System (AHRS) / Inertial Measurement Unit (IMU) which uses triaxial gyroscope, accelerometer, and compass sensors in conjunction with advanced processing and a proprietary on-board quaternion-based orientation filtering algorithms to determine orientation relative to an absolute reference in real-time. With a 1.5+hour, rechargeable Lithium-Polymer battery, the Mini Bluetooth is the perfect hand-held, wireless orientation and motion sensing solution. Highly efficient orientation sensing.

The Yost Labs 3-Space Sensor™ Mini Sensor Family offers the unique option of adding a haptic driver to your IMU/AHRS. Haptic technology provides kinesthetic communication utilizing vibration to help the user to experience a more realistic sensory experience or to set a useful range of boundaries to perform within.
