Finally, the accelerometer has arrived. I order the sensor at Myduino.com. The MMA 7260 is a 3.3V part and outputs an analogue voltage for each of three outputs. This voltge is in ratio to the measured acceleration and to the supply voltage.
Specification:
- Voltage:3.3-8V
- Selectable sensitivity:±1．5g／2g／4g／6g
- Low power:500μA @ measurement mode，3μA @standby ；
- High sensivity: 800 mV／g @ 1.5g；
- Low pass filter
- Size:23x26mm
- Weight: 5 gram
