The Yost Labs 3-Space™ Sensor Bluetooth integrates a miniature, high-precision, high-reliability, Attitude and Heading Reference System (AHRS) / Inertial Measurement Unit (IMU) with a 2.4GHz Bluetooth v2.0+EDR Class 1 interface and a rechargeable lithium-polymer battery solution into a single low-cost end-use-ready unit. The Attitude and Heading Reference System (AHRS) / Inertial Measurement Unit (IMU) uses triaxial gyroscope, accelerometer, and compass sensors in conjunction with advanced processing and on-board quaternion-based orientation filtering algorithms to determine orientation relative to an absolute reference in real-time.
Orientation can be returned in absolute terms or relative to a designated reference orientation. The gradient descent calibration process and high update rates increase accuracy and greatly reduce and compensate for sensor error. The Yost Labs 3-Space™ Sensor system also utilizes a dynamic sensor confidence algorithm that ensures optimal accuracy and precision across a wide range of operating conditions.
The Yost Labs 3-Space™ Sensor Bluetooth unit features are accessible via a well-documented open communication protocol that allows access to all available sensor data and configuration parameters using either 2.4Ghz Bluetooth or USB 2.0 interfaces. Versatile commands allow access to raw sensor data, normalized sensor data, and filtered absolute and relative orientation outputs in multiple formats including: quaternion, Euler angles (pitch/roll/yaw), rotation matrix, axis angle, two vector (forward/up).
The YEI 3-Space Sensor Bluetooth has many features that allow it to be a flexible all-in-one solution for your orientation sensing needs. Below are some of the key features:
