The invention provides a sensing device for a capacitive type touch-control panel. The sensing device which is provided with a capacitive type touch-control panel of a plurality of sensing units is used for sensing the touch state of the capacitive type touch-control panel. The sensing device comprises a first sensing chip, a second sensing chip, a first selecting unit and a second selecting unit; wherein, the first sensing chip and the second sensing chip synchronously generate a plurality of scanning signals and a plurality of detecting signals, and a plurality of scanning signals and a plurality of detecting signals are sent to the first selecting unit and the second selecting unit. The scanning signals are used for causing the first selecting unit and the second selecting unit to output the detecting signals, which are used for receiving the touch state of the sensing unit. The scanning signals control the first selecting unit and the second selecting unit in sequence to output a plurality of detecting signals, so as to reduce the number of detecting signal wires that are used for sensing the capacitive type touch-control panel.
