| Abstract: | 3- axis acceleration sensor MMA7260Q is a single chip device which is developed by freescale based on MEMS.It can sense fall,tilt,motion,positioning,shock or vibration on the three axises in a very high sensitivity.It is small and has low power con- sumption.It has the feature of Selectable Sensitivity which allows you to select different g value among 4 sensitivities.So it can be ap- plicated in various of areas.This paper not only introduces the principle of operation of MMA7260Q,but also involves the design of MMA7260Q in automotive positioning. |
