Soil acidity or alkalinity is also known as " soil reaction ", and it is the acid-base reaction of the soil liquid, depends primarily on hydrionic concentration in the soil liquid.And the current detection to soil acidity or alkalinity is still with the master that is detected as of Laboratory Instruments, analyze by the soil of instrument to sampling and test to reach the object of detection, but because the workload of sampling is large, and sampling process has certain destructiveness to soil, is therefore not easy to soil and accurately detects.
Utility model content
The purpose of this utility model is to provide a kind of timely detection potential of hydrogen, soil acidity or alkalinity pick-up unit easy to use.
For achieving the above object, according to an aspect of the present utility model, provide a kind of soil acidity or alkalinity pick-up unit, comprise the metal probe, amplifying circuit, analog to digital conversion circuit and the display screen that connect successively, metal probe comprises aluminium electrode, insulator and zinc electrode, and aluminium electrode and zinc electrode are divided into the two ends of insulator.Thus, metal probe inserts in soil, and aluminium electrode and zinc electrode form path, produces weak current.Weak current amplifies by discharge circuit, changing the digital signal for representing potential of hydrogen into, showing at display by D/A converting circuit.Soil acidity or alkalinity test can be carried out in time, and structure is simple, easy to use.
In some embodiments, soil acidity or alkalinity pick-up unit also comprises control chip, and analog to digital conversion circuit is all connected with control chip with display screen.Thus, the signal that control chip sends for the treatment of analog to digital conversion circuit, is sent to display screen by result.
In some embodiments, soil acidity or alkalinity pick-up unit also comprises storer, and storer is connected with control chip.Thus, storer, for storing the potential of hydrogen numerical value of acquisition, is convenient to the record of data.
In some embodiments, soil acidity or alkalinity pick-up unit also comprises commutation circuit, and metal probe also comprises copper electrode, and copper electrode is connected with commutation circuit respectively with aluminium electrode, and commutation circuit is connected with amplifying circuit and control chip.Thus, by commutation circuit, select copper electrode or aluminium electrode and zinc electrode to form loop, and then the detection to soil acidity or alkalinity and humidity can be realized.
In some embodiments, soil acidity or alkalinity pick-up unit also comprises the power supply be connected with control chip, and power supply is rechargeable battery.
In some embodiments, display screen is touch screen.
The beneficial effects of the utility model are: soil acidity or alkalinity monitoring device adopts metal probe to detect the potential of hydrogen of soil or humidity, and metal probe is not fragile, long service life.Adopt amplifying circuit and analog to digital conversion circuit to process electric signal, result is shown by display screen, is more convenient to the reading of numerical value, easy to use.
