Aiming at the accuracy and display interface of compass,an electronic compass with beautiful appearance,and functions of orientation,temperature and time real-time display was designed at the ARM9 development platform. In the system, the high-sensitivity and high-accuracy magnetic sensor MAG3110 is adopted to detect orientation, and intelligent sensor DS18B20 to measure temperature. Linux Qt is taken as the development platform of electronic compass graphical interface. The experimental results show that the azimuth accuracy of the compass can reach to ± 2°, the temperature accuracy is up to ± 0.5℃, and the compass can be used in common navigation field.
