Human impact detection using Accelerometer

Hello everybody,
as the headlines says, I want to build a impact detector using Accelerometer sensor, I don't know where to start, can anybody help me in this please.

Can anybody provide me any guide on this or a simple code.?

Thank you

You should start by getting something like the Adafruit 9-DOF breakout board. Learn how to determine the gravity vector using their libraries then look for specific changes in that vector.

Thank you very much for the reply, I will do as per your guidelines
thank you
