Title:
MOISTURE CONTENT OBSERVATION DEVICE, MOISTURE CONTENT OBSERVATION METHOD AND CULTIVATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/208765
Kind Code:
A1
Abstract:
In the present invention, a real leaf and a plurality of artificial leaves are attached to a white background board. A first light source emits reference light of 905 nm to the white background board while sequentially scanning thereon. A second light source emits measurement light of 1550 nm to the white background board while sequentially scanning thereon. A threshold setting/moisture index detection processing unit calculates a relative moisture content of the real leaf on the basis of the intensities of reflections of the reference light and measurement light reflected by the real leaf and the plurality of artificial leaves. The control unit causes a monitor to display a chronological transition of the relative moisture content calculated in a measurement period.
