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,
