摘要：
A sensor device includes: one or more sensor elements each including first and second diode elements connected in series and a sensor driving section. The cathode of the second diode element is connected to the anode of the first diode element. The sensor driving section controls on-off state of the first diode element through changing a gate voltage under a fixed cathode voltage, and controls on-off state of the second diode element through changing a gate voltage under a fixed anode voltage. The sensor driving section drives the second diode element, maintaining a relationship of Vg2(off)
