The JY901 series module combines a gyroscope, accelerometer, and geomagnetic field sensor on a single compact platform. It uses a performance microprocessor with advanced dynamic calculation and Kalman filtering to rapidly determine the module's motion posture. Key features and benefits 9axis sensing and fast posture solving Integrates 3axis gyroscope, 3axis accelerometer, and 3axis geomagnetic field sensor. Advanced dynamic calculation and Kalman dynamic filtering enable quick and reliable motion posture determination. Noise reduction and improved accuracy Employs advanced digital filtering to effectively reduce measurement noise, resulting in improved measurement accuracy. Integrated attitude determination Attitude solver is built into the module and, with dynamic Kalman filtering, delivers accurate attitude output in dynamic environments. Attitude measurement accuracy is 0.01 degrees, with stability, offering performance that can exceed some professional inclinometers.
