Soil moisture monitoring system - a portable soil moisture monitoring system that builds a solid foundation for cold resistance. Recommended model JC-GTS3- Shandong Jiucheng Intelligent Technology, providing high-quality equipment and one-stop service solutions, highly praised and recognized by users. Accurately controlling soil moisture and building a solid foundation for cold resistance are the core functions of monitoring stations to ensure winter safety. Winter crops such as winter wheat and alfalfa have a close relationship between their cold resistance and soil moisture conditions. When the soil moisture content is suitable, increasing the specific heat capacity of the soil can reduce surface temperature fluctuations and avoid damage to crop roots caused by freeze-thaw cycles; Meanwhile, sufficient soil moisture can help crops accumulate soluble sugars, antifreeze proteins, and other protective substances, lower the freezing point of cells, and enhance their cold resistance. On the contrary, soil drought can lead to insufficient water absorption by crop roots, significantly increasing the cold resistance threshold and making them highly susceptible to freezing damage. The 485 Modbus RTU protocol monitoring station is equipped with high-precision sensors that can accurately collect moisture data from the 0-60cm tillage layer with an accuracy of ± 3%. The data is transmitted in real-time to the control center through a stable communication link. Farmers can accurately judge the soil moisture status based on monitoring data. When the soil relative humidity is below the critical value of 60%, winter irrigation operations can be carried out in a timely manner to ensure that the soil moisture content reaches 70% -80% of the field capacity, and to build a strong cold resistance line for crops.

3、 Advantages and Characteristics

A single soil tube sensor can simultaneously measure soil parameters at multiple depths, and the monitoring depth can be customized (less than 1M).

The sensor adopts a low-power design, with a power consumption as low as 0.26W, suitable for long-term unmanned monitoring in the field.

Each layer of the sensor can independently measure temperature, humidity, and conductivity parameters.

The sensor housing is made of imported PC material, which has high strength, corrosion resistance, and no pollution to the environment.

The waterproof level of the sensor reaches IP67, which is suitable for long-term outdoor monitoring.

The sensor measures the average humidity within a certain area, which compensates for the limitations of single point measurement.

The sensor adopts a self-designed spiral measuring electrode to improve the contact between the sensor and the soil, and to avoid measurement errors caused by air gaps as much as possible.

4、 Precautions for use

a. The use of sensors should strictly follow the installation and use instructions.

b. When multiple sensors are working simultaneously, they must be spaced at least 3 meters apart.

c. The measurement principle of sensors is limited, and there should be no electromagnetic cables or strong magnetic radiation interference within a radius of 3 meters from the center of the sensor measurement site to avoid causing huge errors and damage to the sensor measurement.

d. The installation environment of the sensor should comply with the measurement range of the sensor and avoid non-standard behaviors such as exceeding the range.

e. The installation of sensors should avoid environments with strong acids, strong alkalis, heavy oil pollution, and heavy metals.

f. The sensor is a soil measurement sensor, and it is prohibited to use this sensor to measure other substances.

g. The sensor installation environment should not have strong vibrations.

h. Sensors should not be subjected to excessive external forces.

i. Disassembly is prohibited. Unauthorized disassembly is considered non compliant and no further service will be provided.
