センサ装置
Document Type and Number:
Japanese Patent JP6951743
Kind Code:
B2
Abstract:
To provide a sensor which can package a diffuse light sensor part, a photosynthesis effective photon flux density sensor part, and a temperature/humidity sensor part while keeping reliability of respective sensor functions.SOLUTION: In a box 3, a diffuse light sensor part is constructed comprising a light shielding member in front of a partition part 7 of a front rectangular tubular body 5, a translucent member that is a lid part 17, and a photodetector 23 arranged on the partition part 7 in which light is received from a front side. A photosynthesis effective photon flux density sensor part is constructed comprising a photodetector 23 arranged on an upper side part 35 in which light is received from an upper side. A temperature/humidity sensor part is constructed comprising a temperature-sensitive/humidity-sensitive element 25 arranged on the partition part 7 in which temperature/humidity is received from a front side. Those elements 23, 25 are detachably installed by using connectors so that the elements are exchangeable if the lid part 17 or a protective plate 41 is removed.SELECTED DRAWING: Figure 2
