<p>A capacitive sensing device and a detecting method thereof are provided. The sensing device includes at least one detecting plate (11) and at least one reference plate (12) which surrounds every detecting plate. A first wire (13) and a number of second wires (14) are provided. All the reference plates are coupled electrically to the first wire, and every detecting plate is coupled electrically to a second wire. When the first wire and every second wire are supplied with an electric signal, one or more approached or touched detecting plates are detected according to the difference between every second wire signal and the first wire signal.</p> |
