Hi,
Doing a pre-study for a project where touch buttons are considered. Basically a flat plastic surface with a PCB on the backside. The idea is to use something like this: http://www.atmel.com/devices/AT42QT1040.aspx

My question is now, what happens when it rains? The product will be mounted outside. Could rain or snow trigger the touch sensor into believing it was a key press?

Any feedback welcome,

BR
Bjorn

Cheers! Just what I was looking for from a technical point of view. Still interested though to hear if anyone has real life experience from Qtouch and outdoor usage.

I'm currently located in Jönköping.

I have not had real life experience with this topic, though I almost did. You probably know how that works. I will be interested in real life experience on this as well.
I lived in Farsta in 1981-82 whilst working for Ericsson. (trea korv) So I do know snow from that. :)
