GD51-TYF Soil Salt Transmitter IoT SensorScope of application:

It can be widely used in places such as agriculture, forestry, vegetation cultivation, greenhouses, laboratories, etc.

GD51-TYF Soil Salt Transmitter IoT Sensorsummary:

The main components of the soil salinity sensor are graphite electrodes and thermistors for temperature compensation. Connected to the electrode plug by a four core wire. After burying this salt sensor in the soil, the conductivity of soluble salt ions in the soil solution can be directly measured. Stable electrode performance; The electrode has high sensitivity and is particularly suitable for measuring high conductivity, making it very suitable for the determination of soil salinity;

GD51-TYF Soil Salt Transmitter IoT SensorPerformance parameters:

Power supply voltage: 5-24V Power supply signal output: current, voltage, RS485

Salt measurement range: 0.01-0.3 mol/L, with a minimum reading of 0.01 mol/L,

Conductivity measurement range: 0-20mS (corresponding to 0-2000mV)

Minimum resolution: 0.01mS

Voltage and conductivity correlation (linearity): ≥ 98%

Probe protective body: made of high-quality 316 stainless steel, with a length of 10cm and a diameter of 2cm (convenient for insertion into soil) (resistant to electrolysis, can withstand long-term electrolysis, and can withstand acid and alkali corrosion in soil)

GD51-TYF Soil Salt Transmitter IoT SensorMeasurement range and measurement error:

In the range of soil solution concentration from 0.02N to 0.3N, there is a good correlation between sensor conductivity and solution rate, with a correlation coefficient of 0.98 or above. The relative average deviation of multiple repeated measurements of conductivity values is generally within 5%, and the maximum does not exceed 10%.

Balance time: less than 20 seconds.

Lower limit of soil moisture content: The lower limit of soil moisture content that can be tested varies depending on the soil texture. Usually around 20%, as the soil clay content increases, the lower limit of moisture content suitable for the sensor also increases accordingly.
