れ予知センサー。[Claims for Utility Model Registration] A retroreflective photoelectric switch 3 is attached to one end of a soft elastic cylinder 1 made of a polymeric material whose portion is deformed by receiving an external force from all directions of 360° along its entire length. The projector 3a is also connected to the reflector 3 on the other end side.
b, respectively, and the output circuit 5 of the photoelectric switch 3 is turned on and off depending on the increase/decrease in the amount of light received by the light projector 3a based on the deformation of the soft elastic cylinder 1. A light projector 3c of a transparent photoelectric switch 3 is attached to one end of a soft elastic cylinder 1 made of a polymeric material whose portion is deformed by receiving an external force from all directions of 360 degrees over its entire length, and a light projector 3c of a transparent photoelectric switch 3 is attached to the other end. A landslide prediction sensor is provided in which a light receiver 3d is provided at each of the cylindrical parts, and the output circuit 5 of the photoelectric switch 3 is turned on and off depending on the increase or decrease in the amount of light received by the light receiver 3d based on the deformation of the soft elastic cylinder 1.
