LIS331DL MEMS motion sensor 3-axis smart digital output “nano” accelerometer
The LIS331DL, belonging to the “nano” family of ST motion sensors, is the smallest consumer lowpower three axes linear accelerometer. The device features digital I2C/SPI serial interface standard output and smart embedded functions.
The sensing element, capable of detecting the acceleration, is manufactured using a dedicated process developed by ST to produce inertial sensors and actuators in silicon. The IC interface is manufactured using a CMOS process that allows to design a dedicated circuit which is trimmed to better match the sensing element characteristics. The LIS331DL has dynamically user selectable full scales of ±2g/±8g and it is capable of measuring accelerations with an output data rate of 100 Hz or 400 Hz.
Applications
-
■ Free-Fall detection
■ Motion activated functions
■ Gaming and virtual reality input devices
■ Vibration monitoring and compensation

Accelerometer
These MEMS are great!
I worked for two years in Airbag Control Units and we had to use accelerometers. I had no idea at the time they were MEMS (in fact, I did not even know what MEMS are, back then).
So we just went ahead and blindly used them. Only now do I realize what jewels we had on our hands. But from an electronic point of view they were the simplest thing in our schematic.
I only wish I knew more back then...but I guess this comes along with time.

Accelerometer
Yes, it's incredible what MEMS devices are able to do. As mentioned in the article, MEMS accelerometers are used today also in gaming input device. You can find them in one of the most popular videogame consolle (I'm not going to tell its name, but consider it has WIFI capabilities..).
Other accelerometer applications
Interesting...
Now come to think of it, I also strongly believe they are also included in the iPhone.
I saw two different applications on two different iPhones which must be using an accelerometer:
1. The application shows a "Star Wars" type of sword on the display, and generates a "slashing" sound when you move the phone like a sword.
2. The second one simulates those little old hand games which we used to have as kids, when you were supposed to guide a small metalic ball through a maze by tilting the game itself. Now instead of making the entire game of plastic, the maze and ball are drawn on the display, but you still controll the sliding of the ball by tilting the... iPhone.
