Hi221
Hi221 is a 9-axis wireless motion sensor that integrates exclusive sensor fusion and correction technology. It can output the raw data of 3-axis angular velocity, 3-axis acceleration, 3-axis magnetometer, quaternion and Euler angle after sensor fusing. With Micro-USB and wireless output methods, it can transmit data wirelessly up to 20 meters. It is suitable for motion capture in a large space, making human interaction devices, etc.
Data fusion algorithm
Hi221 uses the exclusive data fusion algorithm. The high-performance raw data and the Euler angle and quaternion after sensor fusion have very small data delay and phase distortion (less than 2.5ms). We provide ANROT IMU GUI software to help you do a quick evaluation and test.
Hi221 dongle
Hi221 wireless dongle is used to receive data from one or more Hi221 sensing nodes, up to 15 nodes can be received for each dongle. With USB interface, it can be connected to a host with USB serial port. Use our code examples in multiple programming languages to create your own applications.
