Arduino MMA7260 Triaxial Acceleration Sensor

The MMA7260Q from Freescale is a very nice sensor with easy analog interface. The MMA7260QT is a 3.3V part and outputs an analog voltage for each of the three outputs. This voltage is in ratio to the measured acceleration and to the supply voltage (ratiometric). It has selectable sensitivity by dip switch.  You will need some extra hardware to convert this analog signal to a usable digital one.  The Arduino is really good option for it.  This break board is especially designed for Arduino which has connector that can be easily plug into our IO/Sensor expansion board.

It adapt three acceleration（Xg、Yg、Zg）sensor of Freescale MMA7260,and it supply 1.5g、2g、4g、6g four grade acceleration range and the sensitivity range is 600, 300, 800 200mV/g. Available in the robot, intelligent vehicle, free fallers detection, and what has higher detection sensitivity etc, it can carry out three-dimensional XYZ axial detection, make  corresponding equipment can respond to position, orientation and mobile changes.

Special note : don't inserted and pull the module directly when you don't turn off the power, otherwise it may be damaged, before using this module ,you would better clear static elimination of body, otherwise that may damage the module!

This electronic bricks will extract all pins of X/Y/Z interface,and  you may be directly connect with the sensor shield through sensor cable or analog sensor cable, it support plug and play. The GS2 and GS1 switch can be used to choose the range .
