9 Axis Attitude Detection Sensor is developed based on MPU-9150. The MPU-9150 is a chip integrated with triaxial gyroscope, triaxial accelerometer and triaxial magnetometer. MPU-9150 is mainly used in low power consumption, low price and high performance consumer electronics, including smart phones, tablets PCs and wearable devices. MPU-9150 contains three 16 bit ADC for digital output of the gyro signal, three 16 bit ADC for digital output of accelerometer signals and three 13 bit ADC for digital output of magnetometer signal. It can be widely used in the model of UAV, robot, antenna turntable, solar, ground and underwater equipment, virtual reality, human motion analysis to product devices with low cost and high dynamic three-dimensional attitude measurement.
