FDC1004 measure of sweat on palms

Hi Kojima,

if you touch the sensor with your hand, the capacitance will exceed the 15pf (which is the max value the FDC1004 can convert).

The human body has a huge capacitance vs. GND.

It is understood that a sensor is saturated by an experiment.

Because I want to pick up a small change, FDC1004 is most suitable.

We utilize a shield and think whether you cannot cancel capacitance of the human body.

If the way of the shield includes an idea, please give me it.
