Abstract

A sensing circuit includes a plurality of sensors, a controller, a multiway switch, a linear optocoupler, and a logical control unit. The plurality of sensors are capable of measuring physical quantity, and each of the plurality of sensors is capable of generating a sensing signal in accordance with the physical quantity. The controller is capable of receiving and analyzing the sensing signals, and transforming the sensing signals into sensing events. The multiway switch is capable of selectively connecting one of the plurality of sensors to the controller. The linear optocoupler is connected between the plurality of sensors and the controller. The logical control unit is capable of controlling the multiway switch to selectively connect one of the plurality of sensors to the optocoupler, and generating a control signal to the controller, wherein the control signal indicating the one of the plurality of sensors connected to the controller.
