the following example is for you reference.
Soil moisture meter, also known as non-contact soil moisture meter, is a TDR frequency domain based on the principle of reflection sensor.It can be carried out for different soil layer of soil moisture content of dynamic observation, but also for rapid, accurate and comprehensive observation, so that people achieve a high degree of perception of the soil





Main Advantages:

Embedded plastic pipe
Pre-embedded in a plastic pipe, the main sensor placed in the tube, can be easily removed from the reserved tube, replace the main sensor, easy maintenance, high recycling

Tube up and down to move
Can be moved up and down in the plastic pipe to achieve the soil soil moisture content of the dynamic observation

High frequency detection wave
Emitting nearly 1G Hz high-frequency detection wave, can penetrate the plastic tube, effectively perceive the soil environment

No direct contact with soil
Will not be affected by the salt ions in the soil, fertilizer, pesticides, irrigation and other agricultural activities will not affect the measurement results, data accuracy

Avoid electrode contact with soil
the electrode of the sensor is not in direct contact with the soil and avoids the interference of electricity to soil and soil
