Arduino using MMA7361 3 Axis Accelerometer
MMA7361 3 Axis Accelerometer
This is a rough and ready test using a MMA7361 3 Axis Accelerometer with a Arduino to read and display in the serial window the values.
Press Crtl+Shift+M to display values in the serial display when running the sketch.
Notes this has a SL, Sleep pin that needs to be pulled High, the sleep basically turns off the MMA7361 3 Axis Accelerometer to reduce power use. This may be important if battery's are used to reduce power used.
How to use the MMA7361 accelerometer?

The sensor requires a very low amount of power and has a g-select input which switches the accelerometer between ±1.5g and ±6g measurement ranges.
Other features include a sleep mode, signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and 0g-detect which detects linear freefall. Zero-g offset and sensitivity are factory set and require no external devices.
It's specifications are:
• Supports 2.2V ~ 3.6V or 5V voltage input.
• Two selectable measuring ranges (±1.5g, ±6g)
• Breadboard friendly - 0.1" pitch header
• Low current consumption: 400 µA
• Sleep mode: 3 µA
• Low voltage operation: 2.2 V - 3.6 V
• High sensitivity (800 mV/g at 1.5g)
• Fast turn on time (0.5 ms enable response time)
• Self test for freefall detect diagnosis
• 0g-Detect for freefall protection
• Signal conditioning with low pass filter
• Robust design, high shocks survivability
