Patent number: 9671353Abstract: Provided are apparatus and system for pest detection and a method for detecting pest damage to prevent pest damage in wooden building structures. The apparatus according to one aspect of the present invention comprises: a post-shaped main body extending in a set direction and formed therealong, and comprising a plurality of holes distanced from each other with a wall therebetween, the wall comprising timber which can be despoiled by pest; and a sensor unit allowing attachment and detachment to and from the upper end of the main body. Here, the sensor unit may comprise: a light-emitting unit comprising at least one light-emitting body for irradiating the interior of at least one hole among the plurality of holes; a sensing unit for sensing the light, emitted from the light-emitting unit, in the interior of at least one hole from among the plurality of holes; and a detection unit for outputting a light signal received from the sensing unit as an electrical signal.Type: GrantFiled: March 5, 2014Date of Patent: June 6, 2017Assignees: Gangneung-Wonju National University Industry Academy Cooperation Group, Seolbong Co., Ltd.Inventors: Hyeong Sun Go, Byoung Hoon Lee, Byung Hak Choe, Hyo Tae Jeong, Jong Heon Shim
