Dear Authors

the manuscript is interesting for the NHESS community. It falls within the important trend of self-developed, low costs sensors which in the long run would help collecting higher resolution data for e.g. landslide monitoring with smaller budgets.
From the discussion it became clear that - although it is a brief communication- the major shortcoming was that it did not give sufficient information for colleagues to build and use such device themselves. I agree with the reviewers that this is the main shortcoming.

I therefore decide the manuscripts needs major revisions. After resubmission the manuscript will undergo second round of review.

Thanks for submitting to NHESS and I look forward to resubmission
regards

Dear authors

The reviewer is quite satisfied with the revised version and I agree it is an interesting article that could find it's way into the landslide monitoring community. Only minor technical issues have been asked for.
Loking forward to final version
