In various fields of industry, agriculture and military,there needs attitude angle to give feedback on the movement of the target vector.With the rapid development of today s science and technology, High-tech applications become increasingly and widely used in modern agriculture, thus the modernization of agriculture needs to be supported by intelligent technology. In the process of realization of intelligent, it needs to control real-time feedback on the status of the motion of the detection target.Therefore,the data collected by attitude angle to give feedback on target carrier movement of intelligent devices is particularly important. This paper presents an attitude angle detection system based on ADXL345 three-axis accelerometer,L3G4200 three axis gyro sensor and HMC5883 magnetoresistive sensor. The system uses STM32F103VCT6 ARM Cortex-M3 core-based microcontroller as the master chip. Through acquisition and processing data from ADXL345, L3G4200 and HMC5883, attitude angle data was obtained. Then, nRF24L01 sent the obtained information to the receiver on whose display module shows real-time data. Through wireless transmission, function of real-time detection can be realized. Through the experimental analysis, the results show that abse of the data
