Hello,

I know it is very difficult to deal with capacitive (touch) sensors with battery powered circuits. I read threads about the way to make it work :

- First solution : 2 plates electrodes (1 ground , 2 touchpin). It works very well. Drawback : the design of the electrodes is more complex.
- second solution : keep the circuit attached to a strong ground. This also works, but it's not very handy.

Did some of you have good results with different techniques ?

Emmanuel
