Arduino MMA7260 Triaxial Acceleration Sensor Module

Arduino MMA7260 Triaxial Acceleration Sensor  is used for signal disposal、unipolar low-pass filter and temperature compensation technology because it use low-cost micro capacitive accelerometer and four ranges which is optional for user choosing in four of the sensitivity. This device include a low-pass filter and zero g compensation.This product also provides sleeping mode and so it's ideal choice for products with battery handheld devices .

Arduino MMA7260 tri-axial accelerometer module is base on freescale's MMA7260
tri-axial accelerometer sensor.It have optional sensitivity, , low power consumption, high stability, etc.

Mainly parameters as follows :

1、Sensitivity: 1.5g/2g/4g/6g (optional)

2、Power dissipation: 500uA (Working Mode) / 3uA (Sleep Mode)

3、Working voltage: 3.3 V (Power directly to the chip) / 5V (Powr from manostat at the back of this module)

4、Output characteristic: the X, Y, Z three accelerometer analog output

X Y Z :

  1、Optional sensitivity : (1.5g / 2g / 4g / 6g)

  2、Low power consumption : 500 μA

  3、Sleeping Model: 3 μA

  4、Operation voltage : 2.2 V - 3.6 V

  5、QFN Package ：6mm×6mm×1.45 mm

  6、High sensitivity ：800 mv/g @ 1.5 g

  7、Rapid opening

  8、Van low-pass filter with internal signals

  9、Stable, strong shockproof capability

  10、Lead-free soldering

  11、ROHS

  12、Low Cost

The pin size and description :



1、X, Y, Z - tri-axial accelerometer simulation output

2、GS2 GS1(g-Select1,g-Select2)----Sensitivity range - choose as following :


3、MODE - Enables Settings, work when high level and sleep when low level

4、3.3V，5V ----the power supply port :
     One way : Can directly power 3.3 V to module
     Second way : Can also directly power 5V through the 3.3v manostat at the back of this 
      module,then to the module
5、GND

MMA7260 :

Application :

Drop detect,Dip angle detect,motion detect, and Anti-Theft detect etc, this module can be applied to the robot control, car control, mobile phones, laptops, pedometer etc. This module is designed as symmetry triangle, there are jumper wire for optional range and 3.3V manostat on its back,and this module has the unique appearance, small size, convenient debug Angle reliable work, etc.

This sensor is vailable for the robot, intelligent vehicle, free fallers detection, and action detection etc, and has higher sensitivity. It can carry out three-dimensional XYZ axial detection, and can make three corresponding equipment can respond to position, orientation and mobile changes. Can be used for evaluation and research.
