    Jack-detect (audio) using cap-touch?

    user_247090680

      Hi!

         

      I need to achieve "contact-less" jack-detect for a 3.5mm audio plug. i.e. the tip, ring, sleeve must all be galvanically isolated from the rest of the system, but still being able to know if something is inserted in the jack...

         

      So I was thinking, would it be possible to use either Cap-touch or Inductance-based sensing by wiring up some magic just under the surface-mounted audio-jack together with a PSoC!?
