AM3X: 3-Axis Accelerometer Module
Which way is up?
This tiny 3-axis accelerometer module can operate in either +/-1.5g or +/-6g ranges, giving your project the ability to tell which way is up. Ideal for robotics projects, tilt sensors, vehicle dataloggers, and whatever else you can dream up.
It has independent X, Y, and Z axis outputs ready to connect directly to analog inputs on an Arduino, and we've included an onboard 3.3V regulator so that you can run it from either 5V or 3.3V. It even has a "zero g!" output to detect when the device is in free-fall, so you could connect that to an "interrupt" pin on an Arduino to have your project react immediately if it's dropped!
The module includes mounting holes suitable for M3 or 1/8" bolts, and a flat rear face so you can easily glue it to any surface.
