| Abstract: | The author introduces the structure, principle and function of the three -axis accelerometer MMA7260Q in detail, which is released by Frecseale Semiconductor recently. Its output characteristics with the changed tilt angle are analyzed, and also the tilt angle of an object can be measured by using the accelerometer that senses the gravitational acceleration on the sensor in three degrees of freedom. It has also introduced the calculative equations of the sensor and the interface circuit between MMA7260Q and MSP430. It is proved that the sensor system has the characteristics of low consumption, high precision and high integration. |
