Determining shocks from LIS3LV02DQ reading

Hi,

I’m trying to work out if my unit has experience a shock by using the LIS3LV02DQ. Is there a smart algorithm out there I can use? My device is going to be installed on a 4 ton forklift and will experience general vibration from the engine.

I have set my LIS3LV02DQ to 40Hz +/-6g and 16 bit left justified.

Any suggestion is much appreciated.
