HI @AHolt.1 , the H3LIS331DL has an embedded "peak" detection feature that enables you to detect a signal that exceeds a certain thresholds and lasts at least 2 ODR or more. Supposing to set a proper full-scale (e.g. 400g), you can detect a shock tuning the height of the shock with the INT1_THS (32h) register and its duration INT1_DURATION (33h). Directly reporting from Wikipedia, both of these parameters are equally important for the shock detection:
The form of the shock pulse and particularly the duration are equally important. For example, a short 1 ms 300 g shock has little damage potential and is not usually of interest but a 20 ms 300 g shock might be critical.
Btw, which kind of shock do you want to detect?
Regards
