--------------------------------

Part 1 of this two-part article reviews the concepts and theory of capacitive sensing to help to optimize capacitive sensor performance.


     Noncontact capacitive sensors measure the changes in an electrical property called capacitance. Capacitance describes how two conductive objects with a space between them respond to a voltage difference applied to them. A voltage applied to the conductors creates an electric field between them, causing positive and negative charges to collect on each object (Figure 1). If the polarity of the voltage is reversed, the charges will also reverse.     READ MORE.............

     En esta ocasión presento a uds. in link con la información técnica de los Sensores Capacitivos, Versión en Ingles.  Si tienen duadas o comentarios no duden en enviarlas.... Saludos!! =)
