Provided by the invention is a sensor device for the detection of touch or approach of an object. A server circuit of the sensor device according to the invention is formed in such a manner, that the server circuit alone (i.e. without co-operation with a client circuit) may be used as approaching sensor, at the same time however also together with one or several client circuits may be implemented a sensor network, in which the client circuits preferably are fed with energy with the electric field of the server electrode. |
