Claim 0:
1. A sensor device comprising:
a panel including an insulating layer, a first electrode provided on a first main surface side of the insulating layer, and a second electrode provided on a second main surface side opposite the first main surface of the insulating layer and sandwiching the insulating layer together with the first electrode; and
a control circuit including a first circuit including a timing control circuit and a first amplifier, and a second circuit including a detection circuit connected to a floating ground line and electrically isolated from the first circuit,
the detection circuit including a detector electrically connected to the second electrode, and a first output unit,
during a first sensing drive period,
the first output unit outputting a first synchronization signal,
the timing control circuit outputting a second synchronization signal generated based on the first synchronization signal and having a polarity inverted from the polarity of the first synchronization signal,
the first amplifier amplifying the second synchronization signal and providing the amplified second synchronization signal to each of the floating ground line and the first electrode, and
the detector reading a change in a sensor signal generated at the second electrode.
