    Hi @Rokyy​ , the LIS2DH12 embeds some digital feature such as the Activity/Inactivity recognition (AN5005 p.53). You can set the activity threshold (in this case, the hand rising threshold on e.g. z axis) setting the ACT_THS and ACT_DUR, which gives you an interrupt to be handled.

    Btw, if you want to recognize a more complex gesture to be much more accurate, the suggestion is to use more powerful sensor modules, as the LSM6DSOX. This sensor is equipped with embedded FiniteStateMachine (FSM) and MachineLearningCore (MLC): you can basically acquire lots of hand-raising gestures, you create a decision tree and you write the configuration in the sensor registers.
