Abstract
The invention discloses a corrosion-resistant soil humidity sensor. A sensor body comprises two probes; the lower end of each probe is bent to 90 degrees; the surface of each probe is provided with a plurality of semispherical grooves; the upper end of the sensor body is wrapped by a shell; the shoulder part of an upper screw cap of the shell is provided with a lead wire through hole; the through hole is provided with a compression swivel nut via a waterproof seal ring; the compression swivel nut is a through body with two communicated sides; a lower screw cap of the shell is provided with three through holes equal in size side by side; the two probes pass through the through holes and are mounted on the lower screw cap; a transmission line is connected to an external controller from a detection circuit in the shell; connection parts of the probes and the through holes are provided with gaskets. The contact area of the probes and soil is enlarged; the accuracy and the sensitivity of the soil humidity sensor are improved; the sensor has excellent waterproof performance, and prevents short circuit, caused by interference of moisture, of a circuit board.
Description
Technical field
The invention belongs to sensor technical field, be specifically related to a kind of corrosion-resistant soil humidity sensor.
Background technology
Soil moisture number the growth of crops is had very big impact, the analysis to proportion of crop planting kind of measuring of soil moisture has vital effect.At present, China is just being gradually reduced the distance with developed country on water-saving irrigation automated control technology.Various intelligent controllers are born in succession, the sensor of the various intelligence matched with intelligent irrigation agricultural also can occur in succession, soil moisture sensor on market also emerges in an endless stream, detector is gradually to miniaturization, but owing to the probe of detector is long-pending often less with soil contact, and the single probe of many employings, so the control accuracy of humidity is inadequate.Widely used water transformed into soil water resistance is unexcellent in the market, causes wiring board short circuit when measuring water content higher deep soil in moisture content inflow chamber body.So surface soil can only be measured, it is impossible to measure deeper of soil.
Summary of the invention
For problems of the prior art, it is an object of the invention to provide a kind of corrosion-resistant soil humidity sensor.
The technical scheme that the present invention takes is:
A kind of corrosion-resistant soil humidity sensor, it is characterized in that, including sensor body, housing, testing circuit, described sensor body includes two probes, the lower end of every probe is bent into 90 degree, detecting probe surface arranges multiple hemispherical groove, the upper end of sensor body is wrapped in enclosure interior, the shoulder of the upper blind nut of housing is provided with a wire through-hole, through hole is provided with a gland nut by waterproof grommet, described gland nut is the entire body that both sides communicate, the lower spiro cover of housing is arranged side by side the through hole of three equal sizes, two probes are arranged on lower spiro cover through through hole, transmission line is connected to peripheral control unit from the testing circuit in housing, the junction of probe and through hole is provided with pad.
Further, described probe is fastened by the copper stud of trough of belt and lower spiro cover.
The invention have the benefit that
The present invention is by adopting two probes and being arranged above with groove at sensor probe, increase the contact area of probe and soil, improve accuracy and the sensitivity of soil humidity sensor, it is mounted with waterproof grommet, sensor is made to have excellent water resistance, the higher deep soil of water content can be measured and ensure that sensor internal keeps dry, it is to avoid the interference of moisture content causes wiring board short circuit.
