Model Three shock detection

The Logmore model Three logger uses an acceleration sensor for shock detection. Here are the designated axes for shock directions:

Shock recognition thresholds

It is possible to set a shock recognition threshold for each axis (X, Y, Z). The possible threshold can be adjusted by 0.125g steps between 2g and 16g. The model uses an acceleration sensor for shock detection. (Range 2 ... 16g in 0.125g steps)

After an impact surpasxsing the set threshold is detected, the QR tag's acceleration sensor activates for a 5 second period. During this activation period the sensor measures impacts. The highest recognized value is then saved.

The value will be saved either as only the total highest G-force or the exact values from each three axis during the activation period, depending on the tag settings. All of the saved measurements include a timestamp.

Note: if the hit is not direct on the monitored axis, it must be greater than the threshold more angle there is.
