Capacitive Touch Kit

I’ve got the DFRobot capacitive touch wheel set up and detecting all the segments nicely (using the DFRobot library for Arduino), but it only works with direct contact with the segments. Is there a way this can be made more sensitive? I have looked through the datasheets and the suggested changes to the CPP file, but the changes don’t seem to have made any difference. I’d like to be able to use the touch wheel through a 3mm sheet of acrylic.



It may be possible, but 3mm of acrylic is a tough ask, I don’t think it could reliably work with that much of a gap unfortunately. That product is designed for that type of use case.
