<p>PLANT SENSOR A plant sensor (10) includes a first light emitter (26) to emit first measuring light with a first wavelength to irradiate a growing condition measurement target (cr) therewith; a second light emitter (27) to emit second measuring light with a second wavelength to irradiate the growing condition measurement target therewith; a light receiver (35) to receive reflected light of each of the first and second measuring light from the growing condition measurement target and output a received light signal; a controller (23) to control light emission; a light path merging unit to merge a first outgoing light path of the first measuring light from the first light emitter and a second outgoing light path of the second measuring light from the second light emitter; and a common outgoing light path connecting the light path merging unit to a light exit portion emitting the first measuring light and the second measuring light. - ~ C - C.D )C ini ----------~~~ ~ ~ ~ O tI LLJ *- i -- J u-i o UC cj:: -" > a i i i in C.,;o gL UJ -- ~ -CAIi n~CX s -- J - AJ r I Q:L LLJ / LLJ em cm c I L ,-- rsO- la c=W A ir-= ML 2/9</p> |
