Hi,

For example:

I have a metalic plate in the wall. I want detect when anybody touch this metalic plate.

I saw some touch sensors but do not know if I can put a wire connecting the sensor to this metalic plate.

I saw a sensor using 2 plates and that the person would have to pull the two to the sensor detects. I dont want this. I want a sensor to detect if have a touch in only plate.

Have any idea for this ?

tks,
Celso

Any metal plate will do, even kitchen / aluminium foil.
