UNDERGROUND SENSOR AND UNDERGROUND SENSOR SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an underground sensor having a novel structure, reliably attracting even noxious organisms preferring humidity in particular, by maintaining the sensor to have appropriate humidity, and capable of precisely detecting the noxious organisms in a simple constitution: and to provide an underground sensor system using the underground sensor.;SOLUTION: An underground sensor 10 includes: attracting means 54 for attracting noxious organisms; vibration detecting means 68 for detecting vibration of the attracting means 54; moisture detecting means 74 for detecting moisture of the attracting means 54; reference value setting means 16 for setting a reference value for determining whether or not the noxious organisms exist in the attracting means 54 on the basis of a vibration detection value; reference value correction means 16 for properly correcting the reference value according to change in a moisture detection value; and determination means 16 for determining that the noxious organisms exist in the attracting means 54 when the vibration detection value exceeds the reference value set by the reference value setting means 16 and properly corrected by the reference value correction means 16.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
