HI221 Receiver

Product Characteristics:

H221 / HI221GW is a low-cost, high-performance, small volume, low delay inertial measurement unit (IMU). This product integrates three-axis accelerometer, three-axis gyroscope and a low-power microprocessor. It can output three-dimensional azimuth data calculated by sensor fusion algorithm based on local geographical coordinates, including roll angle, pitch angle and relative heading angle. At the same time, the original sensor data can also be output. Hi221 consists of hi221gw (receiver for waist) and hi221 (attitude module for legs). One hi221gw and up to eight hi221 modules form a star network structure. Each hi221 can output real-time attitude data up to 100Hz.
