Diego, this is terrific. Tasker hadn't occurred to me before, but I immediately started creating some tasks and profiles on my phone after reading your post.

You might consider adding "Interpretation" to your databin so all the values for a given key are automatically assigned correct quantities or put into more immediately useful formats.

Here you can find out standard units for different Tasker variables: http://tasker.dinglisch.net/userguide/en/variables.html.

And then you could do something like this with your example bin above :

SetOptions[
  Databin[MyBinID], 
  “Interpretation”->
     {
      "loc"->"GeoCoordinates",
      "locSpeed" -> Restricted["StructuredQuantity", ("Meters")/("Seconds")], 
      "lightLevel" -> Restricted["StructuredQuantity", "Lux"], 
      "magneticField" -> Restricted["StructuredQuantity", "Microteslas”]
     }
  ]

Another trick I'm enjoying:

Rule[#[[1]], #[[2]]] & /@ Values[Normal[bin[All, {"loc", "magneticField"}]]];
GeoRegionValuePlot[%]

There's almost certainly a more elegant way to handle the first step there, but the output is a nice map that plots the intensity of some selected variable at the point it was sampled.

Yes, Marco, I also thought of your smart phone post right away. If you get any experimenting with iOS done - let us know, I would be very curious. There is new Barometer sensor on iPhone 6 - interesting to test.

You can try IFTTT apps.

Thanks Vitaly! I'm currently logging a snapshot of the variables every 2 minutes. For a better study on my phone usage pattern, I created three additional profiles:one when I turn on the screen, one when I turn off the screen, one when I navigate between applications. I had to remove the wolframdatalog task from them and replace it with a data logger on the phone memory due to the restrictions of a maximum of 60 data points per hour on the free account.

I'll have to search for a similar app for my kid's iphones. Im interested to see how much of their time they spend on their phone. Seems they are always plugged to the device.

Thanks Bernat. Loved your Time Lapse Video and Data Drop example. Please let me know what cool things you got to do with the table.
