Japanese Patent JP2021132738
Kind Code:
A
Abstract:
To provide a contamination detection sensor without depending on image processing.SOLUTION: A contamination sensor 400 includes one or a plurality of electrodes EL, a volume detection circuit 410, and a processing part 420. The volume detection circuit 410 detects an electrostatic capacity of the one or plurality of electrodes EL. The processing part 420 determines the presence/absence of contamination based on the electrostatic capacity of the one or plurality of electrodes EL.SELECTED DRAWING: Figure 1
