Hey, i'm planning on building my own little weather station with my arduino, but my main concern is how i can make it survive rain and moist in the rain, because we all know electronics and water don't mix ;P

i'm planning to equip the weatherstation with a atmospheric pressure sensor, and if that is gonna work i can't put it in a water proof container, because then it wouldn't be able to messure the correct atmospheric pressure :S
And the temprature sensor is a small circuit board, and again that can't be mixed with water or air moist :S

What do i do guys?

PS: I'm not sure if this is in the right forum ;P

Well, an important thing to remember is that rain usually falls downwards, and pressure sensors often have a tube coupler that allows them to be mounted in a dry place, but have the measuring part exposed to ambient pressure.

but when it rains, the air is very moist, won't that give some trouble to the electronics?

here's the temprature sensor:

and here the atmospheric pressure sensor:

Most of it is in danish, but you can read about both on sparkfun

but won't the moist get into that tube and ruin the sensor?
