Moisture click is a Click board™ that can be used to easily detect a moisture level of the skin, by simply touching the sensitive surface of the PCB. The Click board™ is equipped with the printed copper trace sensor, which is sampled by the accurate FDC2112 IC, a 12bit capacitance to digital (FDC) converter, which employs innovative noise and EMI resistant capacitance measuring techniques. This sensor allows the Click board™ to measure the skin moisture by measuring its capacitance, which changes depending on the skin moisture level (hydration state of the outer epidermis).
