This Accelerometer module is based on the popular Freescale MMA7361 three-axis analog accelerometer IC (datasheet here), which reads off the X, Y and Z acceleration as analog voltages. The accelerometer is very easy interface to an Arduino Microcontroller using 3 analog input pins, and can be used with most other microcontrollers, such as the PIC or AVR.
2x5 pin 0.1" pitch pin headers
Two sensitivity modes 1.5G and 6G
5VDC & 3.3VDC operation
0G detect pin (for linear Free-Fall detection)
Sleep Mode to save on power
Integrated 1 pole low pass filter
Self Test Mode for easy troubleshooting
