Abstract: A vital-sign sensor is provided. The vital-sign sensor includes an output/input port, a driving/conversion circuit, a detection circuit, and a controller. The output/input port includes a detection pin. The driving/conversion circuit is coupled to the output/input port and controlled by a control signal. The detection circuit includes an input node coupled to the detection pin. The detection circuit generates a detection signal according to a detection voltage at the input node. In response to the output/input port connecting a sensing probe, the detection voltage has a first voltage value, and the controller detects a type of the sensing probe according to the detection signal corresponding to the first voltage value. The controller generates the control signal according to the determined type. The driving/conversion circuit generates a driving signal according to the control signal to drive the sensing probe.
