Abstract

The invention relates to a capacitive multi-layer soil moisture detecting device. The capacitive multi-layer soil moisture detecting device comprises a shell, a bracket is arranged inside the shell, and a plurality of humidity sensitive capacitors are arranged on the bracket; and a capacitive soil moisture switching circuit is further arranged inside the shell, and the humidity sensitive capacitors are connected with the capacitive soil moisture switching circuit. The capacitive multi-layer soil moisture detecting device is embedded in soil, and the temperature and humidity of the multi-layersoil are detected in real time according to the output pulse frequency.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a capacitive multilayer soil moisture detection device. Background technique [0002] Agricultural production occupies an important position in my country's economic development. With the continuous growth of my country's population and the rapid development of industry, the consumption of fresh water resources has increased, the area of ​​cultivated land has decreased, and the contradiction between agricultural production and land and water resources has become more and more prominent. Among them, how to use water resources reasonably and efficiently under limited conditions will become one of the focuses of agricultural development. A large number of experimental studies have shown that the planting industries such as greenhouse vegetables, greenhouse flowers, and horticultural cultivation have high requirements on soil moisture. Unreasonable soil moisture will no...
