An electrosurgical system includes an electrosurgical generator configured to provide electrosurgical energy to an electrosurgical device coupled thereto which, in turn, delivers electrosurgical energy to tissue. The electrosurgical device may include a plurality of sensors configured to detect one or more tissue properties and output a detected tissue property signal relating thereto. One or more multiplexers having a plurality of channels are electrically connected to each of the corresponding plurality of sensors. The multiplexer(s) may be configured to receive the detected tissue property signal from each sensor of the plurality of sensors and output at least one output signal along a signal line. The signal line is configured to connect to the electrosurgical generator to control a power output of the electrosurgical generator. A channel select algorithm is configured to automatically select channels from the plurality of channels.
