AN OPTICAL LEAF WETNESS SENSOR |
| Authors: | H. Griffioen, J.G. Kornet, K. Schurer |
| Abstract:
A novel design of a wetness sensor is presented that is based on the change upon of the optical reflection upon wetting of a glass-air interface. In a test with five sensors in a Douglas-fir forest, reliable operation over a period of several months was established. Validation of the method in the forest and in a separate experiment gave good conformity of the recorded wetness with more direct determinations. | |
