Planned Experiment

Submitted by digthefalls on Wed, 09/27/2017 - 13:04

Hello!

First, let me begin by explaining that I am the owner of Dig The Falls, which is a website devoted to the surveying and good stewardship of New York State Waterfalls. I have co-authored a book on the subject through Firefly Press and have a great team of people that aid me in data collection.

The plan for my sensors is to send them over the waterfalls to collect telemetry data. 

My question:
What is the most important information to be collected (besides height, which is first and foremost for my survey)?

how to get data out of PocketLab Voyager internal memory

Greetings,

my Voyager has just arrived and if I remember correctly it should carry info about how friendly he was handled on its way to me. But I cannot figure out how to get the data out of internal memory. I use it with Android device and just realtime probing functionality works fine.

Thanks

Aha moment

I'm getting used to the orientation of the axes with my new Pocketlab in acceleration mode.

Initially I was expecting to orient the axes with the z-axis reading -9.8 m/s^2.  Wrong!  (I think.)  Letting the sensor sit on a table with the z-axis upward should read +9.8 m/s^2.  Think of it as sitting on the floor of an elevator accelerating upward.  It feels the push of the table under it (the normal force) pushing it upward.
