Abstract

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 Vg(off)<Vp<Vg(on), and, in off-to-on transition of the second diode element, overdrives the second diode element through temporarily applying a gate voltage Vg(od) to the gate electrode, maintaining a relationship of Vg(on)<Vg(od). Vp, Vg(on) and Vg(off) are the anode voltage, a on-state gate voltage and a off-state gate voltage of the second diode element, respectively.
