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 4-hour, rechargeable Lithium-Polymer battery, the Mini Bluetooth is the perfect hand-held, wireless orientation and motion sensing solution. Highly efficient orientation sensing.
