Meteo pressure/temperature/humidity sensor

Hi! I am trying to build a simple weather station that has to always sit outside hanging on my wind turbine tower. So it is going to be enclosed in a hermetic case. This will require pressure/humidity sensors sit outside of the box but what I have seen so far are simple SMD chips that are not IP66/IP67 safe.

Can anyone recommend such sensors?

Thanks a lot in advance, Sergei

You need a Stevenson Screen to enclose your T and H sensors. The electronics can be in a fully weather proof box.

Well, I see but still a sensor should not sit just on an SMD with open connectors, resistors around, etc. All of this will rust in a matter of days. This kind of screen will protect from direct rain but will not protect from fog which is bad for SMD.

A temperature, pressure, humidity sensor can only work if exposed to the air.

How else can it work?

Of course, but when it is mounted on a an SMD like this http://www.dx.com/p/arduino-digital-temperature-humidity-sensor-module-121350#

it is too fragile to weather. I am looking for something more protected when there is a good and isolated casing for everything (paths on SMD, wires, etc.) except the sensor itself.
