INTELLIGENT DETECTION DEVICE FOR SOIL MOISTURE AND NUTRITION CHANGES

摘要

An intelligent detection device for soil moisture and nutrition changes. A detection probe of the detection device has the characteristics of illegal-pulling prevention, corrosion resistance, and high easiness in carrying, can be buried in the soil for a long time to monitor soil moisture and nutrition, and further performs precision management on plants by means of related data fed back by the device. The detection probe comprises a first electrode (36), a second electrode (34), and a third electrode (33); an insulating layer is provided between the electrodes; the first electrode (36) and the second electrode (34) constitute a resistive sensor; the second electrode (34) and the third electrode (33) constitute a capacitive sensor.
