In this embodiment, controlling means is the singlechip, and nutrient solution monitoring devices is seal structure, and filter housing is equipped with filter housing, is equipped with a plurality of filtration holes on the shell for impurity such as filtration plant roots avoids the root system winding positive and negative electrode, influences nutrient solution conductivity and detects unusually. The housing of the nutrient monitoring device comprises two parts: filter shell 4 and bottom platform 5, filter shell 4 and bottom platform 5 can be dismantled and link, and detection device 1 is equipped with two mounting holes, through the screw with detection device 1 fixed mounting in on nutrient solution monitoring devices's the base platform 5.
In this embodiment, two probes 11 are used for being transversely immersed in the nutrient solution, two probes 11 are parallel to the surface of the nutrient solution, and two probes 11 are at the same distance from the surface of the nutrient solution in the vertical direction. The height of the probe of the detection device is equal and parallel to the water surface when the probe is transversely arranged, and the accurate result can be obtained only when the whole contact pin is immersed in liquid during detection, so that the accuracy can be improved when the probe is transversely arranged compared with the probe which is vertically inserted into water, the detection change is a rapid process when the probe is vertically arranged and the nutrient solution is gradually immersed, the detection time is shortened, and the stability of the detection result is improved. The probe material is preferably a titanium alloy material, so that the corrosion resistance in the nutrient solution is strong under the condition of long-time electrification. In other embodiments, the number of the probes can be multiple, the multiple probes are respectively electrically connected to the positive electrode or the negative electrode, and the positive electrode and the negative electrode are both electrically connected with the probes, so that multiple groups of detection data can be simultaneously acquired for analysis, and the concentration detection result of the nutrient solution is ensured to be more accurate.
In this embodiment, the probe 11 is covered with the liquid level of the nutrient solution, and the control device can determine and display the concentration value of the nutrient solution, that is, the data processing module 22 receives the conductivity of the nutrient solution detected by the detection device 1 through the data receiving module 21, and calculates the concentration of the nutrient solution. When the concentration of the nutrient solution is too low, the data output module 23 sends information to the alarm module 24, the alarm module 24 gives an alarm to prompt that the components of the nutrient solution are too dilute, the concentrated nutrient solution needs to be supplemented, and the nutrient components in the nutrient solution are improved.
