@mfalkvidd I actually mean for something that is assembled already which I can just integrat it.
I look for something like this: http://selfbuilt.net/shop/gy-80-inertial-management-unit
@Gus8 Do you either have a pull-up resistor in place, 4k7 to 10k, or possibly have the internal pull-up resistors enabled for the data line that you have it connected to?

I have not had problems with enclosures per se, but I have seen temperature differentials due to locations exposed to direct sunlight and up against thermal masses such as a external walls or internal walls with enclosed heating ducts or hot water piping. I have four sensebenders in vented enclosures mounted on interior walls and have no problem with their accuracy. They are also loosely mounted inside their enclosures which may help them avoiding picking up heat from the walls. Overall, they seem much more consistent and accurate than the several DHT or Dallas sensors I have in my system.
Thanks for the reply, perhaps my issue stems from my enclosures being mostly sealed. No venting what so ever. I did a quick test of a few of my sensors, opening the boxes and letting them sit in open air and the differentials came down substantially.
Will look in to adding some venting!
@sundberg84
I'll consider it thanks! The price is higher of course but still in the affordable range. You see, personally I find useless to collect data that is inaccurate even if it is cheap. I have been playing with the DHT11 because I found it in the arduino starter kit I bought last year, so for prototyping is ok, but for a real application I'd prefer more accuracy and reliability
@ehome
If you need a minimum range of 5-7m have you thought of radar?
