The Yost Labs 3-Space™ Embedded v3 sensor is an ultra-miniature, high-precision, high-reliability, surface-mountable (SMT/SMD), low-cost Attitude and Heading Reference System (AHRS) / Inertial Measurement Unit (IMU). The AHRS/IMU uses triaxial gyroscope, accelerometer, and magnetometer 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 3-Space™ Embedded v3 sensor features are accessible via a well-documented open communication protocol that allows access to all available sensor data and configuration parameters. 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, and two vector (forward/up).
The 3-Space™ Embedded v3 sensor also offers a range of communication interface options which include SPI, I2C, USB 2.0, and asynchronous serial.
