Tea Garden Soil Moisture Monitoring Station

　　Tea Garden Soil Moisture Monitoring StationIt can simultaneously record the decreasing trend of soil moisture in a certain plot and the meteorological data of temperature rise and wind speed increase during the same period, accurately locate the cause of soil moisture changes (whether it is caused by crop transpiration or meteorological evaporation), avoid the limitation of single soil moisture data that cannot determine the cause, and provide comprehensive data basis for subsequent management decisions.Tea Garden Soil Moisture Monitoring Station

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.
