Description
Technical field
A kind of soil pH value sensor with metal electrode is the utility model is related to, belongs to soil pH value detection technique neck
Domain.
Background technology
At present, in whole agriculture Internet of Things industry, the online monitoring to soil pH value is passed using glass electrode pH
Sensor.As shown in Figure 1, the signal processing converter that sensor includes glass electrode 1, is connected by conducting wire 2 with glass electrode 1
3rd, for glass electrode 1 to be covered on protective cover 4 therein, circuit board is provided with the signal processing converter 3.Glass electrode
PH sensors are the pH value as Laboratory Instruments test solution originally, or are applied in water treatment system, are not appropriate for making
Used for the online sensor of soil, mainly there are following several reasons：1st, the material of glass electrode is very fragile, buries in the soil
It is easily damaged；2nd, glass electrode needs periodically to use chemical reagent clean and maintenance, and otherwise can fail to use, and be engaged in agriculture personnel not
Possesses such operative skill；3rd, sensor is made of glass electrode and signal processing conversion circuit two parts, and volume is larger, field
Between installation lay it is inconvenient；4th, glass electrode pH sensors is expensive, is unfavorable for laying use on a large scale, have impact on agricultural
The promoted extension of Internet of Things industry.For these reasons, agriculture Internet of Things industry is badly in need of new online pH sensors replacement glass
Glass electrode sensor, it is therefore necessary to design a kind of soil pH sensor with metal electrode, can meet industry requirement very well.
Utility model content
Therefore, the purpose of the utility model is to overcome in the prior art the defects of, there is provided it is a kind of with metal electrode
Soil pH sensor.
To achieve these goals, a kind of soil pH sensor with metal electrode of the utility model, including signal
Converter and two metal electrodes are handled, the signal processing converter is using epoxy resin to described in circuit board and two
One end of metal electrode carries out encapsulating and is integrally formed.
The soil pH sensor with metal electrode is provided with output interface, and the output interface connects including RS-485
Mouth or current mode 4-20mA output interfaces.
The material of two metal electrodes is respectively：Silico-aluminum and pure zinc.
Using above-mentioned technical proposal, the soil pH sensor with metal electrode of the utility model, with prior art phase
Than having the advantages that：Compact is compact, installs and lays in field easy to agriculture Internet of Things；Can be for a long time（Number
Year）Work in adverse circumstances, it is completely non-maintaining；Product is solid and reliable, it is not easy to because field farming operation damage；Cost is low
It is honest and clean, being applicable for agriculture Internet of Things can be greatly facilitated.
Brief description of the drawings
Fig. 1 is the structure diagram of glass electrode pH sensors of the prior art.
Fig. 2 is the structure diagram of the soil pH sensor with metal electrode of the utility model.
Embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, the present embodiment（A kind of soil pH sensor with metal electrode, including signal processing conversion are provided
Device 101 and two metal electrodes 102, the signal processing converter 101 is using epoxy resin to circuit board and two institutes
The one end for stating metal electrode 102 carries out encapsulating and is integrally formed.
The soil pH sensor with metal electrode is provided with output interface, and the output interface connects including RS-485
Mouth or current mode 4-20mA output interfaces.Both interfaces can meet over long distances（Tens of rice）Interior signal transmission.
Since the soil pH sensor with metal electrode is installed at outdoor field, use environment is disliked extremely
It is bad, also without the condition of artificial periodic maintenance, therefore it is very high with reliability requirement to durability.So two metals
The material of electrode is respectively：Silico-aluminum and pure zinc.
Silico-aluminum described in the present embodiment can use the aluminium alloy of such as 4000 series, the aluminium alloy category of 4000 series
In the higher series of silicon content, usual silicone content is between 4.5-6.0%.
The ruler of metal electrode can control smaller, therefore electrode effectively subtracts together with measuring circuit integrated installation
The small volume of product.
The engineering plastics shell of selection tolerance soil environment, and epoxy resin encapsulating is used to sensor circuit board, it can expire
The above-mentioned harsh use environment requirement of foot.
Agricultural generally uses battery or photovoltaic system with the power supply of sensor collecting device, there is stringenter want to power consumption
Ask, it is therefore desirable to which the carefully power consumption of design sensor, extends the continuous working period of electric power system as far as possible.
In addition, sensor collecting device be substantially all it is intermittent for sensor power supply and sampled output value, therefore will
Reduce the response time of sensor as far as possible, and save the response time of the important measures, in the present embodiment sensor of power consumption
It is 1 second minimum.
Using above-mentioned technical proposal, the soil pH sensor with metal electrode of the utility model, with prior art phase
Than having the advantages that：Compact is compact, installs and lays in field easy to agriculture Internet of Things；Can be for a long time（Number
Year）Work in adverse circumstances, it is completely non-maintaining；Product is solid and reliable, it is not easy to because field farming operation damage；Cost is low
It is honest and clean, being applicable for agriculture Internet of Things can be greatly facilitated.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.For
For those of ordinary skill in the art, other various forms of changes or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change or change thus extended out
Among the dynamic protection domain created still in the utility model.
