Description
Technical field
The utility model belongs to sensor technical field, is specifically related to a kind of U-shaped multipoint mode humidity sensor.
Background technology
Soil moisture sensor can detect the moisture in soil in real time, is widely used in agricultural water-saving irrigation.At present, the data of single-point when single needle formula soil moisture sensor is measured, can only be obtained, if measure different depth soil moisture content, need to take multiple measurements, sensor be consumed energy and increases, measure efficiency also not high; Utilize module to realize different depth Soil Water Content Rate Determination during existing Multi-point type soil water content sensor design, but be difficult to carry out different depth soil water content mensuration at one time.
Soil moisture sensor is a kind of detection means can measuring soil moisture content in real time, in agricultural production, is especially used widely in agri-scientific research work.But due to the problem in structural design, there is the defects such as measuring accuracy is low, poor real, affect and reduce Detection job in used soil moisture sensor.
Utility model content
In order to solve the problem mentioned in above-mentioned background, the utility model provides a kind of U-shaped multipoint mode humidity sensor, can measure moisture at one time, reach the object that measuring accuracy is high, real-time, cheap in different depth soil.
The technical scheme that the utility model is taked is:
A kind of U-shaped multipoint mode humidity sensor, it is characterized in that, sensor body is set to U-shaped structure, two lower ends of U-shaped structure are respectively straight-bar probe and L shape probe, described straight-bar probe and L shape probe place are at grade, L shape probe and circuit board connect and compose " E " shape structure, straight-bar probe inboard end is connected with circuit board by wire by two of U-shaped probe termination wires, the handle of straight-bar probe is provided with multiple sensor node, the cambered surface of U-shaped structure is provided with polylith display screen, each sensor node of probe connects by circuit board is corresponding with each display screen respectively.
Further, the straight-bar probe of described sensor body and L shape detecting probe surface are provided with chromium coating.
The beneficial effects of the utility model are:
Sensor of the present utility model adopts straight-bar probe and L shape probe jointly to form U-shaped probe structure, achieve the test sensing function of soil moisture, have that structure is simple, measuring accuracy is high, the feature of real-time, cheap, long service life, the handle of straight-bar probe is provided with multiple sensor node, multiple sensor node data can be exported by plurality of transmission lines simultaneously, user can obtain multiple different depth soil moisture content data simultaneously, and this apparatus structure is simple, measures efficiency high.
