i want to buy a accelerometer that can be work in high G (about up to 20G). what kind of accelerometer it this??
What is the lower range? What is the accuracy you need? Waht is the precission? (#digits)
1g The acceleration exerted by the Earth’s gravity on an object or person (for example, a cell phone on a desk experiences 1 g of acceleration). 0-2g The acceleration range experienced by a person when walking. 10-50g The acceleration experienced by an automobile in a typical crash. 100-2,000g The acceleration experienced by a laptop if it is dropped from a height of three feet onto a concrete floor. 50,000g The acceleration experienced by a munition when shot from a cannon.
i want an accelerometer like MMA3201, but it has 3 axis. this datasheet of MMA3201 http://www.alldatasheet.com/datasheet-pdf/pdf/188041/FREESCALE/MMA3201.html
Is 16g enough? Then you could use the BMA180 or ADXL345. Both can be setup to sense up to 16g.

just use one and ignore the other 2? At least you can start building/testing?
