I like to use the
Sleep-to-wake and Return-to-sleep feature of the LIS2DE12. I am wondering what axis value is compared with the threshold value (ACT_THS). Can I select the axis? The
doesn't say much! #sleep #accelerometer #memsSolved! Go to Solution.

All three axis are compered with the threshold value, you can't select them.

Any idea how can I use this feature to detect activity-inactivity? I can't use HP filter on the axes to 'zero-down' the acceleration value because I am actually measuring tilt. Filtered data will only detect the change.

For acitivity-inactivity you can set the threshold above 1g so it will work without any HP filter.
You can also use HP filter for interrupt generator 1/2 and implement the activity-inactivity (or power save mode) with help of you microcontroler. You can wake up the system using threshold interrupt (with HP filter) keep it alive and if there is no more interrupt during some time reduce the ODR and switch the device to power save mode.2017-11-27 09:57 AM
