1)Q:Can it be used in the attic?
A:I really don't know for sure, but I would think unless your attic gets very hot it would work.
2)Q:Will sitting this on a window ledge above the kitchen sink result in inaccurate readings?
A:It's going to read the temperature and humidity of where ever it is sitting. Chances are it's much colder on your window sill than it would be say on your kitchen table.
3)Q:How long do the batteries last under normal usage?
A:Not sure. Mines been on for a couple months and still going strong.
